Alex won't be turning into a ground fighter, it's too late for him to adapt a completely new style, he'll stick to what he knows best and what has worked for him quite nicely.
MMA is all about changing style all the time, and he did very good so far in all of his MMA fights 
Błachowicz is great on the ground, and so is Prochazka but he was better than both of them.
You cant be from Brazil and be weak on the ground with so many good sparring partners.
