Dump OJ Howard?

I had initially drafted OJ Howard and Hunter Henry to begin with. I picked up Delanie Walker since Henry was out. Now I’m second guessing OJ Howard because the Tampa offense does not impress me at all. Now have Waller, Cook, Roudolf, Davis, Witten, Olson, Ebron available. Should I make another swap or am i just being paranoid. Im in a 8 team league…

Pick up waller I say
