I (actually) think that Brett has more than just one more year left in him...
I think that with this change at GM, Brett will have had time to recharge his batteries and come away with a new vengeance for the game - I'd really like to see him come to Lambeau early... and demand (gratuitously) that the WR's and TE's all come early, too! Do it the Majik Man way... work on those routes.. get the schemes down, work out some new wrinkles... get the plan down, plan b, plan c etc.
If the guys on the Team would take it to heart that way.. then so would the Coaching Staff.. We need players who aren't afraid to break down film... "of themselves"... quite a few on the D need to get on board with that. No one's immune.
With Sherman now having much more time to spend on the game plan - we should see a mark'ed difference for the positive... Let's all think positive... One thing's fer sure.. let's say Brett does get us to one more SuperBowl, but then some fluke steals it away... You really believe, he'll walk aaway then? I don't - he'd be smellin' blood and want one more try and (hopefully) make it happen, then step down into history... that's how I see it happenin' - but hey - that's just me. what do I know? Nothing more than any of you, really!
