The AHL is not nearly as good this year as it usually is because of the taxi-squad but calling it a garbage league is a laughable take. Most players who aren't stars spend time in that league, and some stars do as well.
Also, Turcotte probably would have been playing in the AHL right now even if he had played in the NCAA this year, I am a big NCAA guy but if your 1st round pick is playing as a junior in the NCAA it is a bad sign unless the guy is really into academics and wants to graduate or is trying to go the Jimmy Vesey/Adam Fox route. And he didn't get hurt because he was playing in the AHL, he has been hurt the previous two seasons playing in the USHL and NCAA, can't blame the AHL if he's hurt.
