I posted this a while back, but I think Mingo has potential to be a big time football player in the NFL if he's used correctly.
As a senior, Freeney was 6'2" and 250 lbs. per his Syracuse bio. His combine numbers were 6'1" and 266 lbs.
Elvis Dumerville's combine numbers list him at 6'1" and 257 lbs.
Kamerion Wimbley is listed as 6'4", 255 lbs in his 7th season.
Terrell Suggs was listed at 6'4", 257 lbs out of college.
Mingo is consistently listed at 6'4"/6'5" and 240 lbs. If he stayed his Sr. year, he could be around 250 pretty easily.
I think he's got the potential of the guys above. I think Montgomery will be another Will Smith/Cameron Jordan type DE. I just think Mingo has the potential to be a Demarcus Ware or JJ Watts type of playmaker.
