Ball handling. You need at least one wing or off guard besides your PG — who can get it done in the open court. Else we're back to the TO hades of 2 years ago. Richie has the speed & stength to maybe get there in an offseason — but he'd have a lot of work to do, cuz frankly, his ball skills are worse than Knell's by quite a bit, imo.
Whatever Baker's limitations or over-hype, his ball-handling skills make him a more versatile backcourt option than either Knell or Richie.
