I don't think the com parison was intended as an insult at all
I was only 6 at the time, so take it for what it's worth. The Packers had sucked for a long time (Most of the 80s) and were generally considered one of the worst franchises in the NFL. In 1989, Don Majkowski set the league on fire and almost won the division. They would have qualified for the playoffs under today's format (five team qualified back then) in a conference that had Parcells' Giants Gibbs' Commanders, Ryan's Eagles, Ditka's Bears, Seifert's Niners. The Rams and Vikings were no slouch either.
Majkowski was never the same after his rotator cuff injury and soon enough Brett Favre emerged and Don was relegated to obscurity.
I think Tony will have more success than Don did barring injury (in part due to having a better team around him)
