I would've liked to have seen the team sign Garcia or acquire Plummer, but I'm not disappointed. There is still a decent chance we'll get Plummer, because if he wants to keep playing, all he has to do is show up in Tampa with a bad attitude and the team will cut him. There's no way Tampa will pay $15+ million to 3 quarterbacks next season. Or perhaps we could ship a #5 or worse pick to Tampa for him, but that doesn't have to happen RIGHT NOW.
As far as the lack of activity in free agency, I'd rather have no signings than bad signings. We had way too many of the latter due to Casserly's gross incompetence. Going into free agency, I didn't think the team would do more than pick up a few players who could patch holes, and there's still time to do that.
Extending Andre's contract was a good thing, and I expect more good things during the draft.
There's no reason to get discouraged this early into the offseason. Rome wasn't built in a day, and it's going to take some time to clean up the mess Casserly left behind.
