I hear you, and maybe I'm wrong. My reasoning is simply the old school eye test. I just haven't seen it.Respectfully, Nobody has agreed with you because you haven't presented any reason for us to agree with you. We all thought that he would burst out of the gate with the extra practice time. He didn't, because he couldn't figure out how to defend.
Midway through his frosh year at Mason he started putting it all together and he showed glimpses (I think he went off at GW) of what his talent was and really figuring it out. There were other examples as well but that one comes to mind. Then he got hurt and now it looks like hes just back to being a rotational player. Perhaps he lost his explosiveness from his knee injury that is needed to be legit in the Big East.
Seemingly from his stats it looks like he either is going to end up being a role player in the Big East or he will look to drop down a level so that he can be more of the "focal point" of a team.
Was he over hyped? Yeah maybe. Is he above where he should be? Quite possibly. But an athletic kid like Justyn Fernandez definitely has talent, its just a matter of if hes a little over where he should be in my opinion. We've both been watching Mason basketball long enough when you see a kid that is special, and Justyn fit that bill. He might actually end up being a high level player at a mid major level versus doing what hes doing in the Big East.
We all have opinions, and that's mine, based on what I've seen.
But, hey, it doesn't really matter does it? He's not here anymore.
