I really like Crowder as a backup SF and S Johnson as a future starter but im not sure they are a great fit together. They are both very similare types of power SF who can play small ball PF and I think they would hurt each other as teammates. If Crowder is backing up more of a scoring/ 3pt shooting SF then he can both back him up and play along side him at the PF. Playing two guys with the same offensive skill set and limitations (high end 3pt shooting) may prove less then ideal. Of the current draft prospects I think Herzonja is the ideal fit eventually starting with Crowder as the back up but I cant see to many ways he ends up a celtic.
