None of our draft worthy D linemans look as dominant as I had hoped. Not saying they are playing bad, just wanted to see more. As of now, here is what I would guess -
Norton- looks like the highest pick to me based on his play and body right now. When I am not watching for a specific player, he seems to be the most disruptive. I could not see higher than late 3rd at this point without a pretty stellar second half of the season, not sure if he is even considered top 10 at his position nationally and would guess mid 4th.
Thomas - His sack numbers are lacking. His total production is lacking. Say whatever you want, draws double teams, gets held, whatever, he simply is not around the football enough considering his physical attributes and praise coming out of high school. Watch out if he puts up a decent 40 time though. He still has great length, and if he shows the athleticism he looks to have, I could see a team taking him much earlier on potential. 4-6, but that could jump significantly with a good combine.
Mcintosh - Looks like an NFL player, but not impactful enough to be taken in the first 4 rounds currently. Seems to disappear when I am not watching him specifically. That said, may have the longest NFL career of the current DL based on combination of size and athletecism. Mid 5th-7th.
Harris does not strike me as an NFL player due to his skill set and size. If he was bigger I could see a pass rush specialist, if he was faster I could see a transition to LB. UDFA.
