Tutu, Harris and Rochell I can easily see getting some rotational snaps. But by enlarge look at who the starters are in front of them. There are no vacancies for starters. I think Garrett might play before Jones. Jones is raw and has flaws in his game that he can't afford at this level. He's basically Kiser's replacement behind Reeder. In fact he's got a lot in common with Kiser. But Jones will have to make his "bones" on STs this year. Perhaps his biggest flaw technique-wise is his film shows he often has problems stacking and shedding blockers, a big problem for an ILB. It's also coupled with how he was often blown out of his gap assignment. Again I think he might make the roster but on STs for now.
Chris Garrett is a tweener between OLB and ILB. He has good length, and though he lacks long speed he has a very good first step. I don't really see him as an OLB but as an ILB. But regardless of where he plays he will need to strengthen and improve his technique. The problem with his OLB play is his inability to set a hard edge and didn't show the flexibility to bend around a OT in pass rushing. He has shown enough to earn himself a roster spot on STs. If he progresses well I see him in a rotational role next year. Again he's typical of Snead drafting for traits. Garrett has good length, with long arms and a good first step. I don't see him as a starter anytime soon because of his lack of long speed, but he certainly can become a very good rotational LB.
Both the Browns have a whole lot of technique work and conditioning to do before they are NFL ready. The few months of OTAs and camps might not be long enough this year, since so much of it is still virtual and not on the field. Ben Skowronek looks like just a ST player right now. It's his ticket on to the roster, to flash in STs drills in camp.
