Disagree that it made no sense. Disagree that Belichick had to make a decision. It made a lot of sense to keep Garoppolo on. Most of us here preferred having him back up rather than a pick simply because we were within our Super Bowl window and saw no point in not keeping that insurance.
AND given the way the call went down, I highly doubt Wickersham's story that Belichick was ordered to trade Garoppolo.
After all, Lynch called Belichick about the trade. Belichick didn't call Lynch. Belichick wasn't shopping Garoppolo around. Lynch even said that BB hung up on him after he asked for Brady (he was joking). But he said after he got off the phone with Belichick, Belichick called him right back and offered Garoppolo.
This is much less an order to trade Garoppolo or even a plan on Belichick's or anyone's part. It sounds like Lynch called him, and after a moment, Belichick called him and offered Garoppolo.
