Since you seem so sold on how Bradford won games for the Rams, here are his statistics in the wins only:
157/244 (64.3%), 1700 yards, 10 TDs, 3 Ints (Averages: 22.4/34.9, 242 yards, 1.4 TDs, .4 Ints).
Of those numbers, the only good ones is his interceptions, where he threw his other 12 Ints on the year in the 9 losses. However, he only threw above average in three of the 7 wins:
Seattle (Rams won 20-3): 23/41, 289 yards, 2 TDs, 1 Int
Denver (Rams won 36-33): 22/37, 308 yards, 3 TDs, 0 Int
San Francisco (Rams won 25-17): 28/37, 292 yards, 1 TDs, 0 Int
Out of those three good games, the Rams only "needed" him in the last two. So, as CK said, out of the 7 wins Bradford really only won 2 of them, 3 if you're being generous. More than that, in the other four wins he threw less than 200 yards in 3 of them! The fact that every single game they won this year was against a team with a losing record except San Diego is no consolation.
In the following losses, Bradford threw for less than 57% completion rating: NO (56.3), Oak (56.0), Sea (52.8), Det (51.1), TB (50.0), KC (48.8).
In the following losses, Bradford threw for less than 200 yards: KC (181), Oak (167), Sea (155), TB (126)
In the following losses, Bradford threw more Ints than TDs: Ari (1 TD, 3 Ints), Sea (0-1), Det (0-2), NO (0-2), KC (0-2)
Now, is it apparent that Bradford lost more games than he won? Don't bullshit me and say "Oh, he won games because the rest of the offense sucked balls." He did not win more than 3 games this year, and that's being very generous. He lost at least 4 games this year, which is also being very generous (in reality it was more like 6). Hence the negative value from the "obscure website that no one has really heard of."
Finally, you compared Bradford's receivers to Matt Ryan's rookie year. Matt Ryan's top five receivers in 2008 were as follows: An oft-forgotten about 1st round pick that had one good season before 2008, another old 1st round pick that had eclipsed 500 yards only twice before, a backup running back, a rookie wide receiver, and a 32 year old 4th string receiver that hadn't played since 2005.
