Matt Cassel: One-Year Wonder or Franchise Quaterback???

Is Matt Cassel a big bust or the next Tom Brady. If we look back to the 2001 season, we can see the first Patriot quaterback come alive. Drew Bledsoe was a Hall of Fame quaterback until he took a huge hit. Tom Brady was a wonder that year and led the team throughout the playoffs and in the Super Bowl Brady beat out Bleadsoe for the job. Now Tom Brady is in the top two quaterbacks in the NFL. My question to you is: Was Matt Cassel a one-year wonder or a franchise quaterback??????
