Easy! Any QB can benefit greatly by being put in the perfect situation.
The aforemention Mark Rypien:

SB year in 1991... 28 TDs, 11 INTs
Cunningham's best year:

His best year in 1998... 34 TDs, 10 INTs
Granted, Cunningham's best year was better... but you should be able to get the idea... an average QB (i.e. Rypien) can look brilliant in a good environment. And in 1998... in a perfect system with diminished physical skills... Cunningham was just that... an average QB in a great system.
Wow. Now THAT is a pretty bold statement!
There has been some pretty good QBs over the years... much better QBs than Cunningham ever was that come to mind.
Manning, Marino, and Elway come to mind.
Well, he did have some degree of talent around him on offense... it wasn't a total wash.
Mike Quick was a good WR for a few years. Keith Jackson was one of the games best TEs. Buddy Ryan cut Cris Carter. And Keith Byars was a pass catching DEMON out of the backfield. And wasn't Ricky Waters in Philly for one year with Cunningham?
So while Philly's O did leave somwething to be desired at times... it wasn't like Cunningham never had ANY talent around him. He did have some.
And just as I think that some QBs in todays game rely too much on their legs, and not enough on reading defenses to make plays (i.e. Micheal Vick) I think that Cunningham in his prime was the same way. Keep him in the pocket, and collapse it around him while forcing him to make the right read and the game is yours.
And it's nothing more than speculation... but I think that Harrington was put in the same situation as Cunningham in 1998 in Minnesota... that Harrington looks like the second coming of Joe Montana too.
In fact... looking at Harrington's numbers and considering the team around him for his entire career... I don't think that they look that bad.
Granted they are not great... but nor are they Vinny Testaverde-ish (in Tampa Bay) either. In fact, in 2004 he had 19 TDs and 12 INTs... Any Detroit fan will tell you... those ain't Andre Ware numbers there.
