This is on point.
If I can expound on it for a moment, Todd got an absolutely raw real while coaching the Oilers. By the TDL of 2017-2018 he had lost all of Hall, Eberle, Yakupov (not that he was all that great) and Maroon and it was replaced by a group of a struggling Spooner, an inconsistent Strome, a poorly developing JP and the precipitous decline of Lucic. He had his faults such as not line matching but can we please admit amongst ourselves as hockey fans that there was nothing left for him to match with. His inability to adapt the lineup and find solutions in order to get the best he could out of it was as much of the cause of his downfall as it was that there was so little he could get out of the lineup anyway. Line matching? With which of the 3 3rd lines was he supposed to be effective when McDavid-Draisaitl were on not the ice?
Chiarelli ****ed this team into oblivion and it shouldn't come to the surprise of anyone that even Hitch couldn't win much. But to your point he's not a good coach for young players.
The greatest fault I find with Todd is that he allowed horrible habits to develop within the game culture of the Oilers. It was everyone all but standing and waiting for whatever thing McDavid was he was gonna do out there. Because unless it was him warp speeding up the ice there was no break out. Unless he carried it in there was no zone entry. Unless he passed there was no passing play etc. Oh that and running Talbot into the ground so much he dug halfway to China
