Input: Consider 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.

Output: Andrew Luck


Input: Consider Input: Sam Querrey gave the United States a winning start in its bid to reach Saturday's final at the World Team Cup.
 Querrey beat Jan Hajek 6-3  7-5 on Thursday to put the U.S. 1-0 up against the Czech Republic in the Red Group and remain unbeaten in his three singles this week.
 "So far so good " said Querrey. "I thought today was the best I played out of the three matches. So I'm pretty excited."
 Hajek claimed the first break  when Querrey ended a long rally with a forehand error  to go 3-1 up but the American player responded by winning the next five games in a row to take the opening set.
 Both players saved a break point late in the second set before Querrey broke at 6-5  converting his third match point.
 "I've been working this week to try and hit my forehand a little bigger. I felt I did that today " said Querrey. "I felt pretty much anytime I got a forehand  I was able to take control of the point."
 Querrey said his win takes the pressure off the U.S. ahead of Friday's matches.
 "A little bit  yes. I think John (Isner) can go out there and play a little more freely  which is a good thing " Querrey said. "When we have the lead  you can swing away a little bit more than if we were 1-0 down.
 "Then  the Bryan brothers  we expect them to win every match. Hopefully  they are going to do that again."

Output: Sam Querrey

Kyle Stephens testified in January at the sentencing hearing for  Larry Nassar   who was convicted of child sex-abuse charges in a Michigan court. Her cousin Sophia Stephens contributed to the drafting of this op-ed.
Kyle Stephens  who was sexually abused for six years by disgraced gymnastics doctor  Larry Nassar   talks to fellow survivors about the emotional and physical toll and how's she's healing. (Kate Woodsome Gillian Brockell Kerri Pang Jesse Mesner-Hage/The Washington Post)
Sexual abuse is hardly limited to  Larry Nassar   Michigan State University or USA Gymnastics. One in nine girls  and one in 53 boys  will experience such abuse by their 18th birthday. I find the way we ignore or sugarcoat our most vile issues to be offensive and a big part of our problem. Our silence and inaction create a culture where predators can thrive.
