I like Jake a lot, I think he has a great tool-set, but Morgan just seems like he has that "it" factor when compared to Jake. Morgan is more explosive than Jake, he passes better, he skates better (Jake is probably a little more deceptive with his skating), has better hands, has a little bit of a higher compete level, and seems to be better on the hockey IQ department. I take Morgan because I think at the same age he has the ability to be better, but we'll see I guess.
Tough to vote against Gardiner because he had a great season last year, and is more proven because of said last year and looks like he'll only get better. But I would choose Rielly due to the fact that he could potentially be more if he reaches his higher ceiling. But for Leaf fans it is defiantly nice to have both.
