There's still some concern there for sure.
Sherfield is mainly a ST player. Harty could be a nice player for us, but I have a bad feeling that his diminutive size will lead to constant nagging injuries, like another Marquise Goodwin. Shakir is the guy who could really elevate this group. There is reason for optimism given the signs he flashed in his rookie season.
Overall I would rank the unit somewhere in the 10-15 range. Not bad, but you can certainly see why Hopkins has been a hot topic of discussion.
