In order of difficulty for Driver:
Packer Hall of Fame: Of course. There are about 135 guys in already. The WRs already included are Robert Brooks, Boyd Dowler, Antonio Freeman, James Lofton, Sterling Sharpe and Max McGee. I'd rank him 3rd. in this group behind Lofton and Sharpe. You can figure Jennings will get in eventually...he's about on a par with Brooks and Freeman.
NFL Hall of Fame: I'm tempted to say "no way", but I'll be sensitive and say "highly unlikely". Andre Reed, Chris Carter and Tim Brown are lined up and having trouble getting in. There's a pipeline of current and eventual 10,000 yd. receivers in the league now. I'd rank Driver a bit behind Stanley "Steamer" Morgan, who probably elicits a "who?" from voters under the age of 40, and about on a par with Anquan Boldin among current players, and Boldin will pass him soon on career stats. Nobody talks about Boldin as a HOF player; that might change for a little while if he has a big game on Sunday, otherwise not. It's possible you won't see Driver making a final nominations list.
"Ring of Honor": See NFL HOF above. I think there might be a misunderstanding about this honor. First, whatever you call it, it's a misnomer because that series of names displayed around the perimeter of Lambeau field has no official designation. It is actually just a complete list of NFL Hall of Famers who played or coached the bulk of their careers for the Packers. Nothing more, nothing less.
As an aside, Favre is an NFL HOF lock, probably on the first ballot. When he goes into Hall of Fame, he will certainly be added to the "ring". To do otherwise would set a remarkable precedent while marking current management as bitter, foolish d*ckheads, which they are not. And you're hearing this from a guy who thought we should have traded him around 2000.
Jersey Number Retired: No way. There are 17 Packers in the NFL HOF who have not received that supreme team honor; 16 if you count Hornung's #5 unofficial retirement. As for Favre, that's a tough call. I'd lean toward "probably not" in the foreseeable future, but "perhaps" at some future date once the bitterness has faded and the principals are no longer in the front office. One caveat: if there's a massive grass roots petition drive to make it happen, current management and the board may take the path of least resistance.
