I think Gibbons is going by how they pitched their first games. Price said in post interview he was a bit nervous. He didn't pitch well in game 1, not sure if it was the 10 day rest or nerves. Think Stroman isn't phased by pressure so you're gonna get the same pitching from him in game 5 as you saw in game 2.
I like starting Stroman but cannot see wasting Price with a 7 run lead. Time to get him out before he makes this interesting.
