re: Convince me our pass rush will be sustantially better next year.

Miller: 4.53/6.70/246lbs
beasley: 4.53/6.91/246lbs
ware: 4.56/6.85/251lbs
Barr: 4.66/6.82/255lbs (not a pass rusher)
Barwin: 4.66/6.87/256lbs
Avril: N/A; 6.90/252lbs
Rivers: 4.61/6.94/248lbs

not sure how you got some of those when some are missing (Avril) or over the time for the 40 (Barr/Barwin).

Hendrickson: 4.65/7.03/266lbs

also, here are the #s of DEs with 10+ sacks last year
Golden: 4.90/??/260lbs (7.39 cone at proday)
Hunter: 4.57/??/252lbs (6.95 cone at proday)
Wake: 4.65/7.12/236lbs
Walden: ??/??/238lbs
Kerrigan: 4.71/7.18/267lbs
Jones: 4.87/7.07/266lbs
Perry: 4.64/7.25/271lbs
Mack: 4.65/7.08/251lbs
Orakpo: 4.70/??/263lbs (7.26 cone at proday)
Bosa: 4.86/6.89/269lbs
Ford: 4.59/7.07/252lbs (all pro day)
Clark: 4.79/7.08/271lbs

So here's the guys he is comparable to in weight:
Hendrickson: 4.65/7.03/266lbs
Golden: 4.90/??/260lbs (7.39 cone at proday)
Kerrigan: 4.71/7.18/267lbs
Jones: 4.87/7.07/266lbs
Perry: 4.64/7.25/271lbs
Orakpo: 4.70/??/263lbs (7.26 cone at proday)
Bosa: 4.86/6.89/269lbs
Clark: 4.79/7.08/271lbs
