Nice thread, I was wondering when this type of topic would come up. I think at this stage obviously, its too premature to make a declaration like that as Melo is only about a year into his tenure with the Knicks. But I've been watching these guys since the late 80's--when players such as Trent Tucker, Mark Jackson and Kiki Vandeweghe used to roam the hallowed grounds of MSG and I could tell you definitively this is the most talented player to ever play for the Knickerbockers.
I have him being a much more skilled player than any of the greats- that includes anyone from those championship teams to the defensive powerhouses in the 90's.
Ewing, to me, is the greatest Knick ever and I never understood how it could be debated when you speak of the greatest talent in NY who always left everything on the floor. Not his fault his team was garbage, he had 2 CBA players that started and way over the hill types like Glenn Rivers and Derek Harper and a very overrated Charles Smith (who was actually really good earlier in his career with the Clippers.)
I will say I read someones post before who said no one dominated Ewing and that's not true. Shaq had his # all day everyday; I'm almost positive Patrick never did better than Shaq statistically when they faced each other. Shaq was just way too big in the mid 90's and he used to treat Ewing like a ragdoll. I hate to say it so bluntly, but it's true.
Now Ewing never had talent even remotely close to what we have now, so his accolades are that much more impressive based on the fact he was going toe to toe annually with the greatest team of all time and always making a tough, competitive series out of it.
To me Ewing is the greatest Knick of all time and probably the most complete (his defense was other worldly,) but Melo is definitely the most talented player and now his skillset is being maximized to the point where if he continues his torrid stretch, there might be a need to re-evaluate this poll in a few years.
