Yes, but Willy could BE the RISP. If he gets on the bases, he can score far more easily than could Burke. Willy's job isn't to get ribs, it's to be the rib. His speed, his ability to somehow get on base even on dribblers, and his superios defensive skills in Center lead me to believe that he'll get the start. Burke did have a great AB against Termite, though, and so I wouldn't be shocked to see him start. But he could still hit as a PH if needed.
I have faith in Gar. His instincts have proven right time and again.
