Kind of agree but at the same time it's sort of unfair. There is such a wide variety of players at these developmental camps, that an 18 year old freshly drafted not "dominating" should hardly be given the not ready distinction. He's going up against guys who have played in the NHL (Severson, Boosh), guys who have plenty of years of college under their belts and are much older (Coleman, Santini), among others. Not sticking out from a group with all those pieces doesn't mean he isn't ready.
And really, what is there to dominate? Today's scrimmage? It's one game, and by all accounts he played great despite not scoring. What else is there to dominate, the drills? I don't put much stock into that. 3 on 3? Kelleher was there star there, don't read much into that.
