Alec PRO: easy ability to become a quality NT player
Alec CON: it would take too many training weeks to make him salary efficient
I'd keep him but I'm pretty casual right now. If you have higher team aspirations, it'd probably be best to sell him.
Those two players could conceivably be trained together for a season, but anything more than that is pushing it. You'd probably get best value selling one of them now.
