Yeah, I guess that's true. His size advantage over boys will create poor habits, I suppose. My only concern is throwing him into the AHL right away and destroying any offensive confidence he gained in the very small amount of time he spent in the Q and it's not as if he was completely dominating that league with only 9g in 31gp (17g in 46gp including the playoffs) which is like a 24g pace over 80 games (29g pace over 80 if you include playoffs).
My fear is not dissimilar to what happened with Shane Doan when he had two dominating seasons in Kamloops, skipped the AHL due to age, was prematurely rushed into the NHL and then lost all confidence as he floundered around for four seasons in a 4th line role. Somehow he found a way to climb out of the abyss of ruined confidence. On the other hand, in Grenier's case, he's only had 45gp in the Q but maybe it would be best to just start him out in the ECHL as a top-six and if he dominates the first ten games or so with the numbers to show for it, bump him up a level and put him in a top-9 role in Chicago?
I don't know but this guy appears to have HUGE potential yet the danger is that if it isn't developed properly it could be smashed rather quickly, no? Maybe it's just my own preference to play it safe in terms of development. After all, many a sniper have said the key to success is confidence and I'm hesitant to risk that critical aspect so early on. Put him in a good position to have personal success in order to breed more confidence and then give him a new challenge.
