[Q]: Bill Polian   Hall of Fame executive.  His  status as a prognosticator is less solid. (NFL Network)
 Bill Polianâs  track record is undeniable. As general manager of the Buffalo Bills   he  cobbled together the lineups that advanced to four straight Super Bowls. With  Polian  at the personnel helm  the expansion Carolina Panthers advanced to the NFC championship game in just their second year of existence.  Polian  then concluded  his  career by shaping the Indianapolis Colts into a Super Bowl winner.
 He âs in  the Hall of Fame  and deserves to be  even if  his  post-football career as an ESPN analyst has been  shall we say  slightly less successful in the prediction department.
 Polian âs latest forecast involves Louisville quarterback Lamar Jackson  who  he  says is too short â at 6-foot-3 â and not accurate enough to be a successful NFL quarterback.
âI think wide receiver â  he  said  when asked about what NFL position Jackson should play Monday on ESPNâs âGolic and Wingo.â âExceptional athlete  exceptional ability to make you miss  exceptional acceleration  exceptional instinct with the ball in his hand  and that âs  rare for wide receivers. That âs  [Steelers wideout Antonio Brown] and who else  name me another one whoâs like that  right? Julio [Jones] is not like that. This guy is incredible in the open field and [has] a great ability to separate and  again  heâs short and a little bit slight and clearly  clearly not the thrower that the other guys are. His accuracy isnât there  so I would say  donât wait to make that change  donât be like the kid from Ohio State [Terrelle Pryor] and be 29 when you make the change.â
Anyway  it wouldnât be the first time  Polian  has been wrong.

[Q]: Beyond the question of James and whether it 's hard to be his teammate , there are basketball mysteries that will matter much more : Will new addition Jae Crowder help the Cavaliers ' 22nd-ranked defense improve in this regular season ? 
; Will Isaiah Thomas ' ailing hip be better anytime soon so he can fill Irving 's role as James ' worthy sidekick ? 
; Will the Cavs swap their prized 2018 first round pick from Brooklyn for another star as a way of convincing James to re-sign in free agency next summer ? 
Cavs forward LeBron James -LRB- 23 -RRB- high fives forward Kevin Love -LRB- 0 -RRB- during the second half against the Boston Celtics in game two of the Eastern conference finals of the NBA Playoffs at TD Garden . 
.@KyrieIrving on why he did n't inform LeBron James that he wanted out of Cleveland . 
Right about the time Kyrie Irving was dissecting his departure from Cleveland with ESPN 's "First Take" crew during a Monday visit in Bristol , Ct. , Cavaliers pals LeBron James and Kevin Love were strolling the beautiful UCLA campus after their latest offseason workout . 
Only James knows if the timing of his latest Instagram story was intentional , but it was impossible not to notice the polar-opposite messaging . 
Some 3,000 miles to the West , James and Love - having clearly evolved from those days where their relationship was the one being analyzed -- were looking like the NBA 's version of Bert and Ernie . 
In one corner , you had Irving making it clear that his relationship with James was n't good enough to warrant a conversation about the late July trade request that led to his exit to Boston . 
The notion of James as anything other than a world-class friend and teammate was nowhere to be found . 
Stephen A. Smith , to Irving : "Did you speak to LeBron James , or talk to LeBron James , before you or your representatives met with ownership and let them know that you wanted out ?" 
I really do ," James says to the Bruin alum during their lifting session . 
"Incoming freshman , here shadowing , you know , the upper classmen ; he 's showing me around campus right now ," James says with a smile as they walk . 
Kevin Love brought LeBron James to UCLA for a workout and campus tour . 
; Will Irving mesh with Gordon Hayward , Al Horford & Co. and help end James ' string of seven consecutive trips to the Finals ?
