The 6'5" guy has an average Inside Shot and respectable Inside Defense.
His rebounding sucks, though.
Good candidate for SF?
Sure. Bad rebounding is certainly unpleasant, but if I had to rank inside skills for SFs by importance, it would only come third after Inside Defense and Inside Shot. You can work around bad inside shot with the right offensive tactic, but even a defensive zone won't save you from a player with poor defense.
