Just looking at last year's Pro Bowl roster:
Defense end: Khalil Mack*, Raiders; Cameron Wake*, Dolphins;
Jadeveon Clowney, Texans
Outside linebacker: Von Miller*, Broncos; Lorenzo Alexander*, Bills;
Brian Orakpo, Titans
Defensive end: Everson Griffen*, Vikings; Cliff Avril*, Seahawks;
Michael Bennett, Seahawks
Outside linebacker: Anthony Barr, Vikings; K.J. Wright*, Seahawks; Thomas Davis*, Panthers
K. Mack 6-3/250
C. Wake 6-3/263
J. Clowney 6-5/270
V. Miller 6-3/250
L. Alexander 6-1/245
B. Orakpo 6-4/257
E.Griffen 6-3/273
C. Avril 6-3/260
M. Bennett 6-4/274
A. Barr 6-5/255
K. J. Wright 6-4/246 (non-edge player)
T. Davis 6-1/235 (non-edge player)
Again, TJ Watt would be fine. He's 22, 23 maybe. He will get bigger than 252 lbs. with football becoming a full-time job.
This is why you are seeing football people using the terms "Edge Player" and "Interior DL" more and more.
