Because when he was drafted it was pretty much a consensus that he'd take 2-3 years. We are at year three and he's not likely to be in the nhl without and injury or trade, and even then it is not a lock given the rest of the talent and potental that amac may be in the minors. Who said he is ahead of schedule, btw? I have not seen that.
That's fine. I'm not saying he won't get called up, just that he may not be first line. All I'm saying is a guy drafted in the first round in 2013 is not in the NHL right now and won't be unless there's an injury. Then next season he will presumably be battling Sanheim, Myers, and Hagg (and maybe even Friedman, Wilcox, or others). He is not even a lock to make it next year it would seem even if we ditch AMac. Provolone, Ghost, MDZ, Gudas will be here, that leaves two spots. I'd expect Sanheim to be in line for one and Morin for the other...but that assumes we don't sign anyone, trade anyone, or get unexpected help from Hagg or other prospects. Patience is great, but at some point you have to think maybe it is better to either trade him or be concerned that there just isn't room for him here.
