I have to vote No.
He had prototypical size and arm strength for a franchise QB, but the results were B+, as Neurotic Guy stated. Lots of passing yardage is nice, but Drew proved that by itself doesn’t equal wins.
His overall winning percentage isn’t good enough. If he had won more in Buffalo or Dallas he might have changed the narrative, but he didn’t. In addition to his winning percentage, his completion percentage was low, certainly not up to 2020 standards. Then look at his TD to Interception ratios and you can see why he didn’t win consistently. His overall QB rating his 2nd or 3rd tier.
In hindsight his stats show a guy that probably played really well between the 20s but couldn’t maintain that in the red zone. Not enough TDs compared to passing yardage and far too many turnovers. You can’t win consistently that way. I don’t know how many times his teams ended up turning the ball over or settling for a field goal after driving the length of the field, but I think it must have been high enough for Bill to easily make the Decision.
*I met Drew Bledsoe back in 2005. He’s a nice guy. A coworker was good friends with him in HS and he handed out a bunch of tickets to friends and family for a Cowboys-Seahawks game. He had a decent game, but the Cowboys lost. That’s Drew - decent game, good stats, not enough wins.
