I do see that you are indeed confused.
You don't think there's some "recruiting" and talks with high draft picks in particular going on when they draft these guys to make sure they want to play for and have enthusiasm for their team?
Have you ever heard of Eli Manning?
He had a say in who he wanted to play for and it worked out exactly like he wanted it to.
Also Jarquez Hunter specifically let teams know that if they drafted him he wanted to play both ways.
Look it up. You can learn something.
Personally, I would want to draft someone who specifically wanted to play for my team as well.
Call me crazy.
