Putting the likelihood of Wells also contracting Rick Ankiel disease aside... Hill 2006: 26 years old, 99.1 IP, 4.17 ERA, 1.22 WHIP, 90 K, 39 BB Hill 2007: 27 years old, 195 IP, 3.92 ERA, 1.20 WHIP, 183 K, 63 BB Wells 2009: 26 years old, 95 IP, 2.84 ERA, 1.15 WHIP, 60 K, 21 BB At the same point in their careers, Hill never pitched as well for as extended a period of time. Are you kidding me? O.K. In which 15 start stretch did Hill post a 2.84 ERA? I suppose if you sandwich his last 6 or 7 starts in '06 with his first 5 or 6 starts in '07, ignore the playoff start and the six months in between, you could argue Hill outperformed Wells over a similar number of starts. Aside from the overall ridiculousness of your timeframe breakdown, since when is ERA the only way to rate a pitcher?
