As long as you dont play them on the same duo... should be ok
Seriously tho, Mailloux or Barron you are facing the same flaws: decision making and defensive play. They both are supposed to be fast skater and offensively minded. I would personally prefer Mailloux for the "edge" he can bring some times - he's not always physical, but he can be meaner then Barron. Mailloux also has better shot then Barron. So...i'm incline to perfer Mailloux over Barron in general. That said, if to get a blue chip forward you need to give Mailloux (and can't pass Barron) then it is a no brainer.
Down the road tho, Hutson and having one of Mailloux/Barron is not the problem. They need partners that can complement them. Would a Hutson/Reinbacher duo be goog? Can Wifi play as well with Mailloux in the NHL as in the AHL??? where does Guhle, Struble, etc fit after?? Next training camp will be quite interesting to see.
