John Elway never had a five-year stretch anywhere close to that good. Moon had a string of 2-5-3-10-6, Jim Kelly was 11-6-2-3-7-11 over a six year span.
The more I look at Boomer's career, the more fascinating it gets. As you said, not many QBs had a five-year stretch like Esiason's 85-89 run. His Rate+ for this years were 125/118/99/129/122. Anything around 120 is exceptional, and Esiason had 4 of those years. Bernie Kosar had a nice run with the Browns, but he only had 1 year (1987) with a 120 Rate+. Jim Everett had a couple big years with the Rams, but not a 5-year stretch. Randall Cunningham seemed to fit the short peak/long career mold, but Cunningham's passing stats weren't really comparable to Esiason's.
The weird part to me is that if a QB has proven to be exceptional for 5 years, then you'd assume that would mean he's just really good and will have staying power. Esiason was mediocre from 1989-1997. Why? Guys like Bert Jones and (gasp) Daunte Culpepper had dominant runs but were then derailed by injury. I don't remember anything catastrophic happening to Boomer. Its hard to find another QB who had a career like Esiason's. The closest I could come up with were Ken Stabler, mid-70's greatness progressing to downright terribleness in the 80's, and Steve Bartkowski who had a surprisingly good run from 1980-1984 (Bartkowski started 5 games in 1985, had a Rate+ of 124, and lost all 5 games).
I really don't know why Esiason didn't remain a great QB. Perhaps Stabler is the best comparison...perhaps Esiason just wasn't all that into football and after awhile he became just another guy at QB.
