After just a single season, Dolezel returned to the AFL as the head coach of the Dallas Vigilantes.  After the Vigilantes franchise suspended operations, Dolezel joined the Philadelphia Soul as their offensive coordinator under head coach Doug Plank.  Plank left the Soul following the 2012 season, and the Soul promoted Dolezel to head coach.  As an AFL player, he was originally signed by the Milwaukee Mustangs.  In his career, he has also played for the Texas Terror/Houston Thunderbears, Grand Rapids Rampage, Las Vegas Gladiators, and the Dallas Desperados.  Dolezel is also a scout for the Dallas Cowboys. The 2015 Buffalo Bills season was the franchise’s 56th overall season as a football team, 46th in the National Football League, third under leadership of general manager Doug Whaley and first under new head coach Rex Ryan, who signed a five-year, $27.5 million contract on January 12, 2015 after having previously spent the past six seasons coaching the division-rival New York Jets, leading them to two straight AFC Championship games in 2009 and 2010, becoming the franchise’s 18th head coach and the fifth in the past seven years in the process.  Ryan replaced Doug Marrone, who opted out of his contract on December 31, 2014 to take advantage of a contract loophole, fearing the Pegulas were going to fire him, hence the reason the Bills entered the 2015 season looking for a new head coach.  Despite the bold prediction made by Ryan at his introductory press conference, where he stated, “I’m not going to let our fans down.  I am not going to do that.  I know it’s been 15 years since the Bills made the playoffs.  Well, get ready, man, we’re going.  We are going,” the Bills were unable to make the playoffs in their first season with Ryan as head coach, finishing with a record of 8-8 (the team’s first since 2002), making it the 16th straight season without a playoff appearance, which became the longest active in major professional sports after Major League Baseball’s Toronto Blue Jays broke their 22-year playoff drought on September 25, 2015.  It was also the first full season under the ownership of Terry and Kim Pegula (whom also own the Buffalo Sabres), having purchased the Bills partway through 2014 after the death of longtime owner Ralph Wilson in March at the age of 95.  The Bills began their season with an open competition for the starting quarterback position after Kyle Orton, the starter for most of the 2014 campaign, retired during the offseason, so the team acquired free agent Tyrod Taylor, a former backup quarterback of the Baltimore Ravens, who won the competition over incumbent second-string quarterback EJ Manuel and trade acquisition Matt Cassel, the latter of whom the team later traded along with a seventh-round pick in 2017 to the Dallas Cowboys, in exchange for a fifth-round draft pick in 2017. David Cross Campo (born July 18, 1947) is an American football coach and former player.  Campo served as the head coach for the Dallas Cowboys of the National Football League (NFL) from 2000 to 2002, compiling a record of 15 wins and 33 losses.  He has also been an assistant coach for numerous NFL and college teams. Jason Calvin Garrett (born March 28, 1966) is an American football head coach of the Dallas Cowboys of the National Football League (NFL).  Garrett was the offensive coordinator and assistant head coach of the Cowboys before being promoted to interim head coach after the firing of Wade Phillips on November 8, 2010.  He is a former professional American football quarterback in the National Football League for the Dallas Cowboys, New York Giants, Tampa Bay Buccaneers and Miami Dolphins.  He played college football at Princeton University. The 1998 Dallas Cowboys season was the Cowboys' 39th season in the NFL.  Team owner Jerry Jones would hire former Pittsburgh Steelers offensive coordinator Chan Gailey to be the fourth head coach of the Dallas Cowboys franchise. The 2000 Dallas Cowboys season was the 41st season for the team in the National Football League.  Cowboys owner Jerry Jones would promote the team's long-time defensive coordinator, Dave Campo, to be the fifth head coach of the Dallas Cowboys.  This was also Troy Aikman's last season with the team. The 1994 Dallas Cowboys season would mark their 35th in the NFL.  Following their second consecutive Super Bowl title, the Cowboys would see a multitude of changes.  In March, months of frustration finally reached its climax as team owner Jerry Jones and head coach Jimmy Johnson held a press conference and announced Johnson's resignation.  Jones would later hire former Oklahoma Sooners head coach and personal friend Barry Switzer to be the third head coach in franchise history.  After a continue run of dominance in the regular season and finishing with a record of 12–4, the Cowboys fell short of a record third straight Super Bowl title with a loss to the San Francisco 49ers in the NFC Championship game.  The 1994 Cowboys draft yielded only one notable addition to the team, offensive guard Larry Allen and veteran linebacker Ken Norton Jr. left the team to sign with San Francisco. Jerral Wayne Jones Sr. (born October 13, 1942) is an American businessman, best known for being the owner, president, and general manager of the Dallas Cowboys National Football League (NFL) team. Josh Holliday (born September 14, 1976) is an American college baseball coach and former professional player in Minor League Baseball.  Currently the head coach of the Oklahoma State Cowboys baseball team, he was hired to this position prior to the 2013 season.  In 2014, Holliday was the Big 12 Conference Baseball Coach of the Year as OSU claimed the conference regular season championship.  Hollidays' Cowboys pulled OSU a little Cowboy baseball tradition out of the fire and faced Oklahoma on the final weekend of 2017.  The team was in danger of missing out of the postseason for the 1st time in Hollidays tenure at Oklahoma State.  The Cowboys swept the instate rival Oklahoma Sooners (#2 seed going into region play) to claim the last and final spot as the 8th seed in the BigXII Championship.  The Cowboys went back to their traditionion and won just the 2nd Big 12 tournament in schools rich baseball history.  The Cowboys won 16 straight Big 8 tournaments before the formation of the Big12.  The Cowboys became the 1st eight seed (last seed) to win the conference championship and by doing so Holliday got his team in the NCAA postseason for the 5th time in his 5 years at the school.  The season was full of injuries from top to bottom Holliday and is associated Head Coach and current (2016) assistant coach of the year Rob Walton put together a pitching staff that was nothing short of magical.  The Cowboys luck would run out as the were sent to the Arkansas Regional and went 0-2 losing game one to Regional champions Missouri State Bears on a two out bottom of the 9th walk off HR.  Garrett Benge hit for the cycle for Hollidays Cowboys but it wasn't enough.  Garrett McCain would be named 1st team all-American the 25th in Cowboys history he would one of five current Cowboys drafted in 2017 preceded by 11 from the 2016 College World Series club.
