Slaton had very poor technique as a rookie, thus he barely played any. He had to learn to use his girth and it wasn't until around year 3 that he really broke through.
Edit: fact checking myself: Slaton had 25% and 32% of defensive snaps his first two years. But there were many times he was pushed back off the LOS in those early years.
My biggest concerns about our DT is depth (if Clark is injured) or short yardage situations. Sounds like Brooks and Wooden have looked better against the run (though that is a low bar from where they started). Wouldn't shock me to see a waiver wire pickup here.
He is the classic mauler style college T that the Packers often convert to guard due to athletic limitations. He played a bit of both for KC and Philly, but most indications had him more at guard. Especially with Philly trading for another backup T. Philly reporters seem to indicate he was a top backup at G.
Morgan, Walker, Banks, Jenkins, Rhyan, and Tom are pretty clearly the top 6 - with both the top backup at C, G, and T in that top 6. Belton vs Kinnard might be a toss-up for next in line T, but I'm pretty sure Kinnard slots in ahead of Monk, Jennings, and Telfort. Honestly, for as much draft capitol we've spent on the OL, our depth is disappointingly thin.
