If you compare their stats from the last year that each played, I don't think that you can argue that Ty was significantly better than Ben. Each had strengths and weaknesses:Hummer seems like a nice kid but he was truly dreadful last season. Either he improves a lot or Ty plays a lot more than him I don't think it's that complicated.
