Sure it was, but the 2008 team was much, much better than the 2000 team.
Cassel was throwing to Moss, Welker, Gaffney and Watson while Bledsoe had Glenn, Brown, Tony Simmons and Eric Bjornson...
The running game averaged 3.3 yards per carry in 2000 for a total of 1390 yards. In 2008, the team avg was 4.4 yards, 2278 yards total. Don't you think it had an impact on what the defenses were preparing against ?
Also, people are quick to point out that Drew didn't have a good game against Pitts in the AFC Championship, to which I agree. However, he threw for 1 TD in just a little more than an half. Brady, during the entire 2001 playoffs, just threw for 1 TD too. I'm not saying I would have played Bledsoe over Brady, but it just shows that the 2001 and 2001 teams were not as gifted as the current team on offense. If we are to compare Bledsoe's 2000 season stats against Cassel's 2008 stats, then we should take a look at Brady's 2001 stats too. Based on that, the Pats should have kept Cassel, since he is younger and had better stats in his 1st year.
