I gave it a C. This is what I expected Monti to do, although the signings happened earlier and cost more than I thought they would.
None of these guys broke the top 100 free agents on nfl.com or the top 150 on PFF. That obviously doesn't mean they won't be good signings, but it's a little tough to get too excited about them. The D-line needed bodies, so those signings make sense from a positional standpoint. Pff said Murphy-Bunting struggled mirroring receivers and needs to play zone to be effective. That should be interesting. The team did get better today, though, so I can't complain much.
However, the problem with treating free agency like this is that you really have to nail the draft. I wasn't super impressed with his draft last year, so I'm hoping for better things this year.
