A couple days ago the conversation in one of UCrawfords fanposts developed into whether we should be disappointed with Glenn Dorseys performance this year or not.  I decided to do some research on some of the better DTs in the NFL and compare their rookie seasons to Glenn Dorsey's.

Glenn Dorsey 2008  (through 8 games)
0 Sacks 
17 Tackles  (projected to 34)
5 assts        (projected to 10)
1 fumble caused  

Sedrick Ellis 2008  (through 5 games)
1.0 Sacks     (projected to 2.5)
7 Tackles      (projected to 19)
5 assts          (projected to 13)
0 fumbles caused

Warren Sapp 1998  (7 time Pro Bowler)
3.0 sacks
17 tackles
10 assts
0 fumbles caused

Albert Hainesworth 2001    (1 time Pro Bolwer)
1.0 sacks 
21 tackles 
9 asst
0 fumbles caused

Tommie Harris 2004   (3 time Pro Bowler)
3.5 sacks
28 tackles
15 asst
1 fumble caused

Pat Williams 1998    (2 time Pro Bowler)
3.5 sacks
11 tackles
1 asst
0 fumbled caused

So while to this point he does not have a sack (though its not unimaginable that he could pick up one or two in the next 8 games), he is on pace to surpass all of these other great DTs in tackles compared to their rookie seasons.  Whether he will actually do that or not remains to be seen.  But I think this shows us that we should not be judging Dorsey too harshly on his rookie season alone.
