It is unfortunate that Solly didn't pan out. I am not sure if it was because he was playing out of position at the 4, or if he just wasn't as good in game as he was in practice for some reason, or something else happened.
What he did in games was just not very good. He had the lowest 2FG% and 3FG% on the team but took a lot of shots (poor shot selection) and rebounded at a similar rate to the 6'0 Fore even though he was 7 inches taller. We were a better team with Buck at the 4, Solly just didn't produce in games for whatever reason.
