It is more about the number of weapons you have and in what combination, that makes you harder to stop over a longer period of time. If you have the combination of height, speed, great mark and accurate kick for goals, it trumps just having the advatage in speed, great mark and accurate kick for goals.
Anyways, if Fogarty being similar height to Fyfe and Mundy, and if he could be as servicable as either of those two in the forward line, it'd be pretty handy. We also forget there's still plenty of likelihood he could continue to grow and gain height over the next three or four years, creeping up to the 194 or so mark maybe.
