A coach has to manage the bench,. Who goes when. Who's up next. Who's on the PK. Who's on the PP. Rest. Game situations including time, score, zone, physicality. With Boucher trust means a lot. You make mistakes , or you make possibly unnecessarily risky plays and his trust meter edges downward and when he looks down the bench you don't pop out as the next guy he wants up. Hockey is a game of mistakes in many ways. Everyone makes mistakes. Rookies will make mistakes on top of mistakes... Wrong place to be, and gave it away, and lost your man, and cost a goal... So will vets but less likely and the body of work provides a certain amount of predictability of what he is going to get. With a guy like Chabot ..who is used to being very aggressive and thinks attack, the risk he employs will get exposed sometimes in the NHL more , in the AHL less, in Junior much less. Brown too but he plays forward and is more complementary than Chabot who lives to be the guy. Brown is more about the pace, strength, and defensive zone.. Formenton imo, could play 4th line in Guys system as well as a lot of the 4th line options we have.. I don't think its best for his development.. I like that he's getting a taste but just turning 18, I think playing is very important. White although he is not as dynamic as Chabot, can't dish it like Brown, and can't skate like Formenton, would likely have the best chance at sticking and playing under Guy because , White can think defense first. IMO he can and does, and it does hurt his offense, but I also think it would keep him up and he can adjust to have more offense in his focus when he is established as trust worthy to Guy.
