I understand the difference perfectly & IMO it's still way too premature. HOF voters, regardless of what they say publicly, look for two things, stats &/or style points. (Pavel Bure is a perfect example of the latter). Fox's numbers don't jump off the page at you, nor is he that flashy.
Regardless of where you may land on the Makar/Fox debate, there is no question Makar has the numbers & the "it factor", so I would have no problem with it if you said he is on a HOF track. Fox, however, is not in that ball park, sorry.
