You won't get anyting close to Price in a deal based on Mauer or Willin.
And besides, it doesn't make sense to target someone of that immense value anyway. You already have your potential two aces in Strasburg and Chapman. You should be targeting cheaper mid ranged compliments to them. I'd say either someone in the range of Gallardo, Scherzer, and Morrow, or even to the cheaper tier of Marcum, Hughes, Cahill and Estrada. Some reliable mid ranged guys that will be around another 3-5 years.
