Hard to say, Coogledukes.
However, what he has to learn to do is much harder than a WR learning the O. He has to retrain his instincts, which is very very tough. He's been playing a certain way his entire football career. Prolly played Pop Warner, so like 10-15 years. And suddenly, what he's been doing in wrong. So, he has to develop instincts, he has to get to where he's playing correctly w/o having to think about it.
At present, he is slow off the snap. Why? Mazi has a nice first step. However, he has to think about what to do, which takes away that first step quickness. It will take a bit yet for him to get to the point where it's automatic. We will not know what type player he is until that happens.
When will that happen? Now that is hard to say. Some learn in TC, some take just a few games, some take much longer. So, we simply won't know until it happens.
Mazi was a very raw talent coming in. If our org. didn't know that, then they are dumb indeed.
