I'm a little worried about Gardnier because of the system he will be forced to play. Carlyle is a defence first type of coach and I think this will hold back Gardnier's offensive development which is one of his biggest strengths. I hate when coaches try and force players into systems when you know it just won't work.
Fowler seemed to do pretty well offensively with Carlyle. I think he'll be fine, Kessel is the one that takes the biggest hit production wise imo.
