As a Jets fan, I wouldn't touch any of them.
Pace is SLOW and has hit the decline as a Rush OLB, just as Bart Scott has at ILB. Scott has a little more value a purely a runstopper, but under no circumstances should he be on the field covering anyone. The Jets are gonna talk to him at the Combine about a small, 1 year deal as Scott and Rex have a great relationship.
To easily speak on Eric Smith, he's a white Roman Harper, let that process for a second
He can be in the right place, just not athletic enough to make the actual play. In the famous Tebow run against the Jets in '11, Smith was the guy who lost containment and whiffed. He has several illegal hits under hit belt on the likes of Boldin and Welker.
I think Rob Ryan has his own personal retread list for the 3-4 anyway. Elam, Kenyon Coleman, Brodney Pool, etc...
