I know there are many savvy minds here who can do a more comprehensive effort than this, but I thought I'd throw together a quick and dirty comparison of our starting rotation as currently configured for 2010 against the abomination that was 2009's rotation. Here are Bill James's projections followed by the 2009 totals. I used Bill James because it's easily available on Fangraphs. SP W L ERA GS IP H HR BB SO ER Wolf 12 10 3.87 34 200 191 24 67 159 86 Gallardo 12 8 3.53 31 186 157 17 84 205 73 Parra 7 9 4.59 28 147 158 13 67 130 75 Bush 6 6 4.29 20 107 112 16 27 74 51 Suppan 7 10 5.09 28 152 175 20 54 81 86 2010* 44 43 4.22 141 792 933 90 299 389 371 2009 55 59 5.37 162 891 999 145 381 658 532 Obviously, the 2010 projections are missing 21 starts, which would presumably be picked up by replacement starters and would probably make the numbers less appealing. And I'm assuming the incumbents will retain their spots in the rotation, although that's far from a safe assumption. I know Bill James is usually very optimistic for hitters, but this looks like extreme optimism for pitchers as well, which doesn't seem to make sense. I'd say this is pretty much the absolute best we could hope for and I'd be shocked if Bush, Parra, and Suppan put up those ERAs. A 4.22 ERA, by the way, would have been 7th in the NL in '09. Another oddity is the 107 projected IP for Bush. Other than last year, he's been extremely durable, so I'm not sure where that's coming from. What do you think? Are these projections reasonable? If so, has Melvin done enough to improve the rotation? Do other projection systems differ dramatically from Bill James? Discuss...
