To be fair, from photographs, it is clear that Rock has lost weight since that game & by report a couple of months later he was getting multiple dunks per game...so demonstrating more athleticism as his back injury moves further in the rear view mirror.
However, although I am very happy to welcome him to the UConn family, he will likely be a work in progress but may get some important minutes against teams with effective bigs (remember he was rated as the #11 player in Georgia this year...many UConn players, Boat for example, were players of the year in their states).
