I'm pretty sure many people could make a good team out of
Forwards: Krejci, Bergeron, Kessel, Marchand, Lucic, Savard
Goalies: Thomas, Rask
Defence: Chara (stud Pronger like no.1)
This is the group Chia had on day 1 of assuming control of the Bruins from Jeff Gorton (who is the one who drafted Marchand, Lucic, Kessel, and traded for Rask ... he is the real architect).
Mac T or Lowe could also look like a genius if given that on the first day of the job, there are no real big positional weaknesses there, there's even two damn good goalies, lol.
In Edmonton where Chia has not had the benefit of such a complete roster from day 1, he's making far more mistakes and being exposed far more, which makes sense because he never had to do any of this stuff in Boston.
All he did in Boston was add grinder/role players next to their core pieces and get bailed out by a Leafs/Kessel offer sheet (basically) that turned out much better than it should have.
