I get why owners may not want to spend a high draft pick and a big bonus on a kid who might quit the game after a few seasons. But I’m not going to cast aspersions on the player for that. They’re the ones taking all the risk.
I agree that these issues are much more important when you are talking about higher draft picks in the NFL. But the players aren't taking
all the risk--even if they are taking the more significant risks (i.e., health). Wasting time, money, and a roster spot for a year or two is something. And you also forgo the opportunity to draft another player.
Long story short, if the team is trying to build a roster and win, it is going to be interested in any and all factors that might may impact their selections. Forget the owners, think about the GM who doesn't want to be fired in 2 years because the team isn't meeting expectations. Their jobs are on the line. They want to minimize risk.
And the short-term nature of the NFL actually probably makes the issue more important. The man or woman who is willing to sacrifice everything for their career is usually more valuable to the organization in the short-term. In the NFL, long-term workaholic burnout isn't the big concern since careers are so short.
As for Rosen, the kid always seemed like he thought he was the smartest person in the room. That can be difficult to manage in any organization.
