Taggart - he's good up the middle, good run defense, pursuit isn't bad, pass coverage is his weakness, he left the middle open a lot for TEs this year, and I think his speed is not quite NFL.
Kelly - this guy is all around good, also a little weak dropping into coverage, doesn't have the speed to run with a WR, great lateral closing speed though, and that's what the tapes will show, he could very well be a full time edge rusher
Glasker - underweight for NFL, he's like a heavy safety playing LB, makes him sneaky fast, puts him in position to really rush the edge and to play the flat, he can drop into coverage and break on the ball, faster than he looks. That Kingston return where he basically escorts a guy running the sideline to the endzone, money. I think his upside is if he can gain weight without sacrificing his speed. He currently isn't big enough to take on a beefy RB and drop him in his tracks.
