Mallett’s in his last year, but I think they will hang on to him. There’s no way Garoppolo is ready to be the #2 right out of the gate. Like Brady before him, he’ll spend this year as the #3, then compete for the backup position with a free agent next season.
Long-term I’d be more interested in keeping Garoppolo regardless. I just haven’t seen enough progress out of Mallett. Mallett has a top-notch arm, but in the preseason games I have not seen his touch improve much, if at all.
