4 AFC championship games and only 1 superbowl. 1/2 more and no more SB wins would definitely be underachieving. To only win one with a HOF QB, TE, and WR is tough. But the Bills lost 4 superbowls with a HOF RB, WR, QB, and DE so its possible. Marino and Kelly have no superbowls, Brees 1 and Rodgers 1. It's tough to win the big one. Manning had 1 his entire career at Indy before going to the superteam in Denver. I think Mahomes/Allen are the top 2 QBs in the league for the next 10 years. I expect both to win at least 1 more in the next decade.
