I've mentioned him in previous posts. He's been on the edge of roster cut-down time with CIN for a couple of years. IND put him on their roster in their SB year. I don't think he got in a carry, though.
That blocked punt was nice - but the thing about him is that he has the keen eye for blockers, offensive and defensive. He's not a juker. However, he is lightning fast after a hand-off and can turn the corner and get through a mess in the middle. I'm surprised that he hasn't been picked up by some club, if only for his overall ST play.
There are plenty of good players out there - but roster limits, other position needs, contracts etc. conspire.
A good front office always combs the backwaters... and the Bills should take a hard look at the cut LB Darryl Blackstock. If CIN's Maualega's knee injury takes a turn for the worse, Blackstock will get the phone call.
