Some of the best DT's/NT's that I've ever seen control the line of scrimmage, at all levels, are on the short and stocky side. And it doesn't translate into big time stats. Like
Ish88888 eludes to above, there's a saying in the trenches that "low man wins". In HS ball our 5' 6" 225 NT would cause hell for the 6' 2" 275 G or C by getting under their pad levels and being strong enough to drive them in whatever direction wanted. Warren Sapp comes to mind as perhaps the best ever in this mold.
Would love to see Shy get a crack at this FB spot too if he and coaches feel that'll get him onto the field if surpassed on the LB chart (hoping not b/c would love to see Shy rush the passer; again, quickness and pad level win). Have no idea if that's ever been discussed.
Was looking forward to seeing what Jesse Connors brings to the table; his measurables, athletic history, and reported skill-set reminds this fan of Tony Fiammetta who was obviously a much higher rated recruit coming out of HS. Is he still nicked up? Haven't heard much about him since Spring ball. Would like to see a guy like him motion as a TE, then into the backfield, or vice versa, in order to create match-up issues for others or allow the QB to audible into something advantageous..
