Collie's brain is a bit scrambled still. I doubt he ever takes the field again (for any length of time at least). I think he will go into coaching once he heals up. He's a super intelligent guy, loves football, has great skills and natural talent. I can see him becoming a WR coach at the college level almost immediately if he so desired and working his way up from there. He has great form when catching the ball and running after the catch. His route running is also great.
I know firsthand that family members have asked him to walk away. Others have told him to keep playing as it was just a fluke thing that KEPT happening. As somebody who cares about the kid on a personal level, I would love nothing more than for him to go out on his own terms and put up massive numbers and retire after 10 seasons or so of high level play. But on another personal level, I get physically ill every time I see him laying on the field not moving and his eyes just making Austin not appear to be Austin. Concussions seem to be no big deal for most fans. Then you go watch your own child play in their first game of whatever sport they choose and try to be the cool and composed parent, but they may hit the field and be down, and your first instinct is to run out on the grass or court and carry them off. Growing old sucks.
