You guys forgot some other important stats:
Patriots without Brady 11-5 (with a guy who hadn't started since HS and is a very mediocre NFL QB).
Colts without Manning: 2-14.
Brady hasn't won crap since his D went away.
Although those that are not fans of Brady continue trot that phrase out as "proof" of something, all it proves is that they are biased and will seek any excuse to justify their stance.
I.
In 2007 the Patriots won 18 games with Brady
In 2008 the Patriots won 11 games without Brady
Net difference: seven wins
In 2010 the Colts won 10 games with Manning
In 2011 the Colts won 2 games without Manning
Net difference: eight wins
That's before also taking into consideration (a) the ease of the Pats 2008 schedule (faced the two weakest divisions in the NFL, the AFCW and NFCW) as opposed to the 2007 schedule (NFCE and AFCN), (b) the steep decline in the rest of the Colts roster heading into 2011, as well as their injuries that year, and (c) the very real possibility that they were tanking in the 'Suck for Luck' sweepstakes.
II.
Matt Cassel had spent three full years in the Patriots organization learning the system; what he did or did not do in college is irrelevant. The fact that he has gone on to be an NFL starter elsewhere makes bringing him up a moot point. About the only thing that shows is the difference in the two team's philosophies on building a roster: the Colts throughout the 2000's were very top-heavy in money spent on their talent and content to fill out their roster with a comparably larger number of low salaried rookies; the Patriots preferred to focus more on the middle third and bottom third of the roster.
III.
It sounds to me as if you are implying that if a team does well without a certain player than he is not that great. Do you think Joe Montana was not particularly good? When Steve Young took over for Montana the 49ers won just as many games in the following season as they had previously with Montana. According to your argument you either don't think much of Montana, or you are a two-faced hypocrite.
IV.
Brady hasn't won crap since his D went away.
It's ironic because this point actually works against your argument rather than for you.
We agree that the Pats defense has not been very good over the last two years, and not even close to the level it was at from 2001-04. Yet despite that during that time the Patriots have won 29 games and a conference championship.
Care to explain how that could possibly be?
Bottom line: just because something gets repeated often, it doesn't make it a valid statement or rational logic. All it points out is that you have a pre-conceived bias and will grasp at anything to justify the close-minded lack of objectivity.
