The more I read about this kid the more excited I am about signing him. As long as his heart is not an issue (health-wise, not in terms of his character or "drive"), he appears to have serious talent.
Someone else said this already, but here are some players the Pats have essentially picked up for "free" (i.e., not in the draft or by trade) that could potentially be big contributors next year:
Demps
Armstead
Ballard
That's a special teams rocket who could be a big play guy at RB/WR, a potential pass rusher, and a very good TE.
Not a bad haul three months before the draft!!
