Input: 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.
