Overall, our DB group is deep and talented. The roster has undergone a bunch of recent shuffling. Roster has Stoutmire listed at S + those guys above, so I'm not worried. They slotted Colton Hood (he is 5'11" 190, so big enough to play) at DB, hence Stoutmire moved, he is 205. One other guy I have seen listed as both S and ILB is Adonis Forrest. A friend drove him into Boulder and said he is physically impressive. He is listed 6'4" 215. He was #9 S out of JUCO. CU roster had him listed at both positions until just recently, however it looks like he is running with the ILBs for now, but that could change.

If the Dline plays as advertised, the LBs are serviceable, the back end of the defense should be fine.
