It's not uncommon for athletes coming off of injuries to take a full year to recover both the full, pre-injury function of the injured area (hips will definitely affect burst movements like stop-start and jumping) and to recover the confidence to move like you did before. OC's athleticism was not off the charts last year, but it is clearly reduced some this year.
I think we all need to look for some progress as the season concludes - albeit with weaker performances mixed in as you might expect from any underclassman - and overall improvement next season after a full summer of time in the gym working on both fitness and his game. Omar is definitely a scorer, and I expect to see him return to form. Let's all give him some time to get there. Thankfully, having Kromah + Giffey (even Samuel) gives us the luxury of not absolutely needing OC at his best this year.
