Still unsigned: Colts WR Austin Collie

A review of the best member of the 2012 Indianapolis Colts who’s still unsigned:

Austin Collie, wide receiver

But for concussion issue, Collie could be a high-quality slot guy serving as a regular and reliable target for a quarterback.

Four years after he was drafted in the fourth-round out of BYU, he might be finished as an NFL player despite an expressed desire to continue to play.

"I'm playing,'' he told the Indianapolis Star after the season. "Right now, it would take a doctor to tell me, 'You can't play anymore.'"

Collie missed 22 of 64 games in his time in Indianapolis dealing with multiple concussions and then a serious knee injury. Minus the health concerns, he’d certainly have a team right now. The Colts likely would have tried to keep him.

Now, however, even receiver-needy teams are surely wary.

Sign Collie and see him take one bad hit, you could see him suffer another concussion. You’d be putting his long-term health at further risk and have a hole punched in your receiver depth chart at the same time.

It’s a sad story. But I would be be surprised to see him resurface.

Others still unsigned include: Offensive tackle Winston Justice, defensive tackle Antonio Johnson, and running back Mewelde Moore.
