If Babin and Peek win the OLB spots in camp then Wong would certainly be an ideal (though expensive) backup for both positions. This teams all-around depth is getting to be quite impressive with the versatility that players like Wong, Pitts, and Coleman are expected to show.
I like the idea of Wong competing with Foreman for the ILB spot as he was quite successful as a MLB with the Vikings, but we haven't heard anything from the coaching staff on that possiblity.
My guess is that with the amount of uncertainty that still remains at OLB asking Wong to try and compete for the 3-4 ILB spot and the ROLB spot would get too convoluted at this point. Perhaps we'll see this as a possiblity in next year's off-season if Peek and Babin show out this year.
