I see things clearly alot differently then you do,for you it's all about performance ,no allowance for allowing a team to adapt to significant changes in roster,especially compared to teams going for it.
And if coaching is such an issue how do explain for example last year,at the 30 game mark they started the sell off moving Luchuk, they were in 4th place, 1st in the league on the PP,2nd in the league in PK,then moved Brown,Day,Vilardi,even though he didn't suit up here,Mceneney, wound up 6th,dropped in PP and PK,especially PP.
My point being when Letowski had more talented players they were right there and not trending downwards, this year somewhat similar, they were trending upwards when Dipietro was dealt, and that was irrespective of a few underachieving players 3 or 4 of them.
Last year after some struggling the last quarter of the season they went 9-6-2 the last 17 games of the season, this season I am seeing similar things last quarter of season,the the team has adapted better and better,they are on on pace to scoring more goals then
last year,goaltending has come around, see only brighter days ahead.
