I don't see Adalius staying on the outside. I dunno why you think BB will switch to a 4-3. The debate has been up time and time again, we've had the personel for it yet it never happens. I don't think we'll ever see it because I think Bill likes having his LBs on the field. How many years has Bill actually ever stood behind a 4-3? Two maybe?
Adalius played on the outside a lot this season, not being nearly as effective. I think some people are seeing something and reacting to it way to fast. I like Adalius as an OLB too, but I think he was brought here to be an ILB and that he will continue to be.
We have Colvin coming back who will either restructure or be cut, but I seriously doubt he hesitates to fix his current number. Plus, with AD and Vrabel there is no steep learning curve for the ILB position because both guys have experience in it. Then I think you work to bring in a pass rusher or talk to Miami for Taylor. I dunno what kind of package we could offer that would work out for us overall though.
