Continuing my look at the top 10 unrestricted free agents for the Carolina Panthers is a player who added experience and depth to the offensive line last season.

Next up: No. 5, OL Fernando Velasco

Reason to re-sign: Just what I said in the introduction, he brings experience and depth to the line. Plus, he can play both guard positions and center. He started seven games last season between left and right guard. You want to hang on to players with that kind of versatility. He's 30, so he has a few more good years left in him.

Reason not to re-sign: Not a lot of good ones, other than the Panthers are looking to upgrade their entire line and the interior seems set with Pro Bowl center Ryan Kalil, right guard Andrew Norwell and right guard Trai Turner. If you're looking to overhaul the backups, Velasco could be a casualty.

Prediction: I say he'll be back. I keep coming back to added depth and his versatility.
