Q: Lincoln-Way East defensive end  Devin O'Rourke  knew the significance of stopping Homewood-Flossmoor from scoring on its first series of the second half.
With  O'Rourke  leading the charge  East forced H-F into a three-and-out and the offense responded with two straight scores for a 29-7 SouthWest Suburban win in Flossmoor.
"The defense knew it had to stop them "  O'Rourke  said. "We did that and the offense came up with the score. This is the best defense I've played on."
The 6-foot-6  250-pound  O'Rourke  not only was a force on defense  the Northwestern recruit provided the offensive line with some firepower when he substituted in at right tackle.
 O'Rourke  hadn't played on the offensive line since his freshman year. He's more than willing to step in when needed.
"I'm used to attacking on defense "  O'Rourke  said. "It's been a little different blocking. It's a little tiring going both ways  but it's fun when we score and celebrate."
Max Cesario  Sam Broda  Dylan Shelton and  O'Rourke  had seven tackles each for the Griffins. Shelton   O'Rourke  and Pedersen recorded sacks.

Q: The good news for Indy is that the only coaching vacancy still looks pretty attractive â if  Andrew Luck  is healthy.
 Luck   meanwhile  continues to be the big question as  he  rehabs from last January's surgery for a partially torn labrum in  his  throwing shoulder.
Some believe McDaniels' sudden change of heart was related to doubts about  Luck 's health.
On Wednesday  though  he attempted to alleviate lingering concerns about  Luck  while acknowledging the franchise quarterback still hasn't thrown a football since returning from Europe late last year.
"At this point  we feel very strongly that  Andrew  is in a good place.  He  doesn't need surgery " Ballard said. "I have not gotten that from the two doctors that  he 's seen here after the season.  His  strength is good.  He 's working on  his  throwing motion and  he 's working on  his  arm speed right now.  He  has not picked up a football  but  he  is throwing balls  working on arm speed.
" He 's going to do everything right to get  himself  ready to play and I'm very confident   he 's very confident  that  he 's going to come back and prove a lot of people wrong " Ballard added.

Q: The leader of India's main opposition Congress party   Sonia Gandhi   has retired from  her  post  the party confirmed on Thursday.
 Her  son   Rahul Gandhi   has been elected unopposed as the new president and will officially take charge on Saturday.
 Mrs Gandhi   71  has been the party president since 1998.  She  was elected to parliament in 1999.
 She  is  however  not retiring from politics and will continue as a member of parliament  the party said.
 Mrs Gandhi  entered politics in 1994   three years after after  her  husband  former Prime Minister Rajiv Gandhi  was assassinated.
 Her  power derived from being the head of the Nehru-Gandhi dynasty  which has led the Congress party and has ruled India for most of the years since it became an independent nation in 1947.
After distancing  herself  from politics following  her  husband's death   Mrs Gandhi  was initially seen as a reluctant and almost reclusive politician.
Under  her  leadership  the party turned in its second-worst performance since independence in the 1999 elections  but won the general elections in 2004 and 2009.

Mrs Gandhi  an Italian-born Catholic  would have been the first foreigner to become Indian prime minister had  she  not surprised everyone by turning down the post after  her  general election success in 2004. Yet  many considered  her  the de facto head of the Congress government.
In recent years  Mrs Gandhi  has faced health issues. In 2011   she  had surgery in the US for an undisclosed medical condition and in 2013  she  was taken to hospital from parliament after falling ill.
