Please. Explain to me how Ricky should have even been in the running for a "Comeback Player of the Year" award, which, no matter how vague it is, is typically supposed to reward someone who came back from something, either concrete, like an injury, mental illness, or something that hindered their play and left their futures in doubt, or something abstract, like rebounding from poor seasons (like Drew Brees) or adversity.
Ricky Williams LEFT THE TEAM voluntarily, still with a lot of gas left in his tank, and returned the same back he pretty much was when he left (not saying he hasn't improved over how he was in 2003, but he was not a bad back then either).
I don't see how he should have garnered any votes.
As far as Teddy Bruschi, please keep in mind the award isn't titled "OMG PLAYER WHO STOPPED PLAYING BUT RETURNED AND HAD MOST YARDS AND MOST BANG BANG AND MOST GUSTO WHEN HE PLAYED", it's comeback player of the year. I'm guessing some voters thought returned from a stroke was more impressive, and some thought returning from a debiliating injury and putting up near MVP numbers was more impressive. Personally I'd go more with the former, but I'm not inclined to insult people who vote for the latter.
