Where in the world do you get this idea?
Dorsey - 6'2" 297lbs: 51 games/179 tackles(83 solo)/13.sacks for -93yds/27stops for loss of 123yds/4 pass deflections/ caused and recovered a fumble
Ellis - 6'1" 309lbs: 48 games/144 tackles(74 solo)/17.5 sacks for -130 yds/28.5 stops for loss of 158 yds/13 pass deflection/ caused 2 fumbles, recovered 4
Ellis can bench over 500lbs, benched 225 more than Dorsey (36 to 27), had a higher vertical jump (30" to 25.5"), and was faster in the 40 (5.01 to 5.14).
Now, while these are all stats and may not measure certain "intangibles", every place I have check says pretty much the same thing about both. "Non-stop motor" excellent instincts, etc.. I am not by any means saying one is BETTER than the other. You can decide that when they have both been in the league for 5 years. Truth be told, they have both had injury issues throughout their college careers, I think it's just that Dorsey's were more recent that people always bring his up.
BUT, what I am saying is that to say it isn't even close is a little far fetched. What I am also saying is what it would take for us to move up to selct Ellis in the draft is MORE than worth it vs. what it would take to move up to selct Dorsey. I am just thinking big picture in for what I see as two VERY comparable players.
