Pure Gold in Bold, as the writer answers his own questions without even knowing it!:
"Most importantly, especially for Belichick -- and maybe not so obvious -- is that Brady has more of a knack for running Charlie Weis's offense, or to put it more aptly, Weis has more of a knack for designing a rudimentary scheme for a beginning quarterback.
The Weis-Brady combination is the major force that beat back Bledsoe, not the rookie quarterback, and that is just a scary message to send to the other 50 guys on the roster: Since our offensive coordinator is unable to design an offense that protects our best QB and feeds off his considerable talents, we're going to stick with our second-best guy as we try to make the playoffs.
Sounds crazy to me.
It was apparent when Brady took over how much more in synch the offense was -- not to mention how consistently, if not spectacularly, the Pats used their running game. Weis gave him more readable patterns and simpler options. He now keeps receivers in the flat and tight ends blocking longer.
With Bledsoe, Weis was always more concerned about tricking the opposing defense than giving his quarterback a chance to succeed based on his talent.
Empty backfield, five-receiver sets with deep crossing patterns and no safety valves. Bledsoe is good, but no QB is that good.
Ha ha ha! No QB is that good, except Brady, of course, a few years later.
