This was Savoie's first true pro season and he did a pretty good job in the AHL. To claim this is his ceiling is premature.
The main add for Oilers in this trade wasn't Savoie but was the cap space. Oilers fans would've been fine had we traded McLeod for a late 3rd rd pick.
Savoie would be a potential cheap replacement for J.Skinner next year or Arvidsson the following. He doesn't need to be doing much more than that on a team that has its core established already. (assuming McDavid extends).
We would have a lot bigger problems than Savoie if McDavid doesn't extend
