Agreed on all. Honestly Peters and Thompson are the only ones I can see being a first rounder ever, and that's really just based on TBS hype for Thompson. Shelton and Kikaha are not first round type DL's.Shelton, Kikaha, Thompson, and Peters will need enormous season's to be considered first round picks. All very solid, Peters to me has the best shot at being a first round pick.
Kikaha had comparable numbers to the DEs that got drafted in the first round last draft
Jackson Jeffcoat was a 5 star recruit, had 13 sacks last year, and was Big 12 defensive player of the year. He went undrafted. Kikaha has torn his ACL twice and is somewhat small for a 4-3 DE. There's more that goes into drafting than their stats.
