JPP, according to Wiki, is 6-5 and was 270 at the combine...ran a 4.71 40. He had 6.5 sacks at South Florida the year he was drafted. I'm not sure Mingo will be as effective at 240 as a 4-3, down on the ground DE.
Sam is more of the JPP size and I'm sure Spags can coach him up.
Now, Justin Tuck was 6-4, 256 at the combine and rand a 4.62, 40. He is now listed at 268.
Just based on height, weight, and 40 time, I'[d take a chance on either, but my gut is saying Sam.
