There are opinions all over the map on what is right and wrong, with strong arguments on all sides. SB Nation has an article explaining the sides:
“Put yourself in their shoes, an injury could change the course of the rest of their lives,” the veteran NFL personnel man said. “We’re not talking about a left guard here. We’re talking about a skill (position) player who is a huge target. That’s the reality of it.
“Look at what these coaches are making now. Those guys are making $5 or $6 million a year and they may pressure these kids to play? Look at what these coaches and ADs are doing. It’s OK for them to leave, but it’s not OK for players to think about their futures? For coaches to (be critical), that’s incredibly selfish. Hold on a second here, guy. You pressure these kids to play, and then one of them (suffers a career-altering injury) and it’s, ‘I love you, and you’re a great teammate. Sorry about that.’ And it’s all for some bowl game who no one cares about? That’s a joke. I’m looking at it practically. If it was your son, what are you gonna say?”
Bruce Arians, the Arizona Cardinals Coach, doesn’t seem enamored.
“That would concern me. Depending on what their situation is as a team, because this is a team sport. But you’ve had a couple of guys get injured in the last couple years. Agents have a lot to say about it. Parents have a lot to say about it. But, it would concern me.”
