No matter what this guy will NOT touch my roster. I made a big mistake in trading for the bum last year and it really costed me. He might get 18 wins, but the Guy posted a 5.00 ERA. In Roto I value a pitcher who can post a 2.50 ERA higher than a pitcher who can win 20 games.
A 5.00 ERA I dont want any pitcher with an ERA over 5.00 on my Roto team no matter how many wins they will get.
He has the potential to implode with any start and he is unreliable. If its a H2H league than maybe you could use him for a spot-start or something, but even that is a risk. As for Roto! No WAY
