Remember also that Kelly ran his offense from the field, calling all the plays and running a fantastic no huddle offense.

first of all, Kelly was named to 5 pro bowls, not 4. didn't play in the 5th..
at the time he went into the hall of fame he had one of the highest career passer ratings..
I think many people view Kelly as a great QB,who ran into 2 SB juggernauts: Redskins, and Dallas (2x)
the Giants game could have gone either way..there was No WAY the Bills were beating the Redskins, and they had the slimmest of hopes against the great Cowboys teams of the early 90's...only 3 players in NFL history reached 30,000 yard mark faster than Kelly. In 11 seasons, he led the Bills to the playoffs 8 times, of those 8, they played in 4 SB's..at the time of his retirement,his passer rating ranked 6th all time, and only second to those QBs already in the HOF, and he also ranked second in number of seasons throwing for MORE than 3,000 yards.
he ranks 2nd all time in post season passing yards..
and, he spent a few seasons in the USFL BEFORE coming to the NFL...he has a higher lifetime comp% than Marino and a higher passer rating than Elway.
yeah,there's no comparison..
Boomer was a great stat compiler, while Kelly was a champion, he won 4 straight championship games. that is unbelievable!
