I simply think he had a good run in his first few years. Then it was all not so swell. Basically, right after the SB appearance, other than Forte (as you mention as I forgot him!) JA couldn't find much in the draft.
Other mentionables:
Cutler as a FA
Vasher, who did well for a while.
Even a broken clock is right twice a day...
I'm not sure about the GB players for the pro bowl...
