I think the biggest issue will be do we stay with Spagnuolo and the 4-3 or buy into a 3-4 using Martez Wilson (Jack), Curtis Lofton (Mike), David Hawthorne (Sam), and Jonathan Casillas/Will Herring (Will)?!?

If we go 4-3, we still are going to have to replace Sedrick Ellis and Will Smith (Salary Cap & Declined Play)...

Don't forget about Chamberlain.

He played well for the Rams last season as an OLB, and he looked really good in the preseason before his season ending injury. He seemed fast on the field and made some nice tackles in the running game if my memory serves me right.

Oh, and he already played in Spags' system in St. Louis.

Chamberlain would be an undersized Linebacker in a 3-4 system; but could he play Strong Safety? Doubt it...

If we stay in a 4-3 Defense, he's expected to push in the WLB spot and play special teams, again one of Steve's guys...

Well, only Herring has more size than Chamberlain out of the Saints' current LB corps, so if we are talking about converting into a 3-4 and doing it with the current roster - he'd be a valid candidate for that OLB position. And in any case, he has enough size to work as an OLB, because there are other LBs around the league who have been successful at that position who were either similar or smaller in size than Chamberlain. I think it's more of a case if his skill-set fits that role, and he seemed fast, agile enough to cover receivers if need be, and a sure tackler, so based on that I'd say he could work in this new position.

Naturally, Wilson would be a clear choice to be moved back to the LB position under the conversion, but other than him, the Saints really don't have prototypical 3-4 OLB linebackers.

on the other side of Wilson... why not junior. He has the size and speed to play the position.
