LB's are a key part of the 3-4 defense. With Bruschi declining and getting close to retirement we need another ILB. Guyton looks good but fits the WILB role, which Mayo is already playing. We need a SILB. The SILB is usually a bit bigger and attacks the line more. LB's from this years draft that fit this role: Rey Maualuga, Jasper Brinkley, Clint Sintim, Brian Cushing. Any others? While I like Brandon Spikes he seems like a similar player to Mayo. More of a WILB play maker. James Laurenitis isn't suitable for a 3-4. Here's a blurb I found on 34 Linebackers that id thought Id share... Mayo will be a starter at WILB for the next 10 years. We need to fill the spot beside him so he can roam around freely and make plays. How do we go about filling this role.
