It even went as far as them bringing in other QBs to workout. They had two guys scheduled to come in, then once Brady got injured they cancelled the visits. Theory at the time was that they were trying to upgrade from Cassel as the backup, but Brady's injury accelerated the timeline. They knew they weren't getting a brand new guy up to speed in a week, and they didn't want Matt looking over his shoulder. Cancelling the visits was an unspoken vote of confidence for him, even if in truth they were thinking of eventually moving on from him. Worked out pretty well considering, just too bad they couldn't sneak in for a House Money kind of playoff stint.
