I'd like several more years of greatness with Rodgers at QB.

Except he almost retired or demanded trades the last 3 years, and even Woody Johnson is scared he's only playing one more year... so the "several more years" part is wishful thinking. There's a better than 50/50 chance by Rodgers own admission (if we believe him) that he's done after this year. He's 39, even he doesn't think he has several more years. I don't know why you do.

The "greatness" part might also be wishful thinking, if you watch the last 21 games of Rodgers tape. The moments of greatness are fewer and fewer. That, combined with his cost, are why people don't see it the way you do.
($60M for 8-9 or 10-7 and a WC loss? yuck.)
