Of course it all depends on how you assess the draft.
Good picks:
1. Aaron Rodgers
2. AJ Hawk
3. BJ Raji
4. Clay Matthews
5. Bryan Bulaga
6. Nick Perry
7. Ha Ha Clinton-Dix
Bad picks:
1. Justin Harrell
2. Derek Sherrod
3. Datone Jones
Not included: Damarious Randall
Obviously we can argue these all day. Hawk was a dependable ILB for 8 of his 9 seasons, not befitting of a #5 slot but that's still good production. Nick Perry is a good player but just can't stay healthy. Tough to say that it was a bad pick. I threw Datone into the "Bad Pick" category because he still isn't a starter, which in my mind is the first criteria to meet as a 1st round pick (I guess that should apply to Perry too but Perry shows more when on the field). Randall hasn't played two seasons so we don't have enough to judge. Early results would say he goes into the first group.
So right there TT is at 70%. You could move Perry or Hawk down but I would say either way that he's doing pretty good. I judged Mike Sherman as going 2 for 3 (67%) in the first round, Wolf at 7 for 11 (64%), Tom Braatz at 2 for 6 (33%), Forrest Gregg at 2 for 3 (67%), Bart Starr at 8 for 11 (73%), Dan Devine at 3 for 5 (60%), Phil Bengston at 1 for 3 (33%), Lombardi at 10 for 13 (77%), and Vainisi at 7 for 11 (67%).
