This signing fits with what I posted in another thread. The issue is at OLB with the potential loss of Lewis who I think will go on IR with the option to return. Hollins fits the mold of what they are looking for at OLB. He has excellent length, with elite speed which contrasts with Okoronkwo who has poor speed off the edge and lacks the physical metrics for the position. That said he's a long way from being a starter. IMO they could be looking at a possible replacement for Ebukam if they are unable to sign him at the end of the year. Clarity will come if they begin rotating Ebukam with Brockers at DE and play Hollis at SAM. This signing also frees up Brockers if they decide to move him inside instead of playing SJD.
Hollis is more polished and faster than Williams who was cut. That said Hollis needs to improve his technique and as I mentioned he's got a ways to go to be a finished product. The one glaring weakness is he is under-strength to play in the NFL. So give him a year to train and body build and he could be a very good OLB next year. I see him getting a lot of snaps rotating between edge and SAM. The SAM position is one of the more challenging positions in the front 7 and it's why it's crucial for the Rams to have someone like Hollis to backstop Samson should they not be able to re-sign him next year.
I find it strange that a prospect like Hollis who was a 5th round pick was cut by the Broncos. The Broncos who run basically a similar 3-4 hybrid scheme viewed Hollis as a "tweener". Which makes no sense. They even tried to fit him into an ILB role. If he can simply strengthen without losing his speed he would be a classic SAM or JACK LB. It would seem the Broncos were looking for an immediate starter that you are not likely to find in the 5th round. Those players have starting potential but are far from a finished product. Ebukam was drafted in the 4th round and earned his chops in rotation, to become IMO one of the best SAM LBs in the NFL. The Rams scheme is a perfect fit for him and I hope they can keep him as he is clearly an impact player.
