Hard to do alternate reality. On paper, Prior would have likely helped in 2003, but our offense was shut down pretty well in the ALDS that year. 3 runs in game 1 behind Santana, then only 1 run each in games 2, 3, and 4... not sure if Prior could have helped. 2004 might be a better year. Prior was hurt early in the season, but returned for the second half and finished strong. Would have meant AJ at catcher, and no Joe Nathan at closer, but I think we would have survived those changes, just like we survived Mauer's injury. The offense did reasonably well in the ALDS that year but we scuffled behind mediocre to poor starts from Radke and Silva. Seems likely that adding Prior to that team could have at least set up a Game 5 full rest start from Johan. But vs the Yankees, we probably would have found a way to screw it up regardless. (Had we advanced, it would have really changed history -- no Red Sox comeback vs NY...) It's a bit more of a stretch to look back at 2002 -- would we have promoted Prior in time? Would he have contributed that quickly for us? But if he could have replaced Rick Reed, either overall or in the playoff rotation, that might have helped. Reed struggled in both of his starts that postseason, putting us in a 2-1 hole vs Oakland, and preventing us from going to LA up 2-0 on the Angels which would have prevented the series from ending in LA. Prior was still decent in 2005 but fading by season's end, and the Twins finished well behind Chicago and Cleveland. By 2006, of course, Prior was cooked, and Mauer was greatly out-performing AJ too. Target Field was finally approved in May 2006. I don't think that would have been affected much.
