Compounding the abusrdity of the derived math in his scenario, is the fact that he supposedly is factoring in for Mauer playing First Base full-time, not Catcher. If you click one level deeper in his skewed schema, with Mauer playing Catcher, he projects Mauer batting at: Davenport @ Catcher: .286/.366/.429-------->.795 OPS BABIP: ~.324 AB: 483 Davenport @ First Base: .277/.356/.409----->.765 OPS BABIP: ~.325 AB: 537 The numbers for Mauer at Catcher are near the other low-ball projection I could find, from ZIPS, only ZIPS has these numbers with Mauer, but at Frist Base: ZIPS @ First Base: .292/.378/.414----->.792 OPS BABIP: .334 AB: ~510 The other projections from Rotoworld are all computed with Mauer as a Catcher, and all suggest much better performance numbers, and the composite-derived-BABIP and OPS from the 3 projections are much more realistic: OPS @ .820 to go along with a very fair BABIP @ ~.342: [TABLE=class: PlayerGrids] [TR=bgcolor: silver] System Position Team AB R HR RBI SB AVG OBP SLG OPS BB K Value [/TR] [TR=bgcolor: #edcece] Composite Catcher MIN 533 79 12 71 3 0.296 0.384 0.435 0.820 75 96 $19 [/TR] RotoChamp Catcher MIN 515 83 11 72 2 0.283 0.375 0.421 0.796 74 95 $11 Steamer Catcher MIN 560 79 14 76 3 0.297 0.388 0.439 0.827 83 102 $22 CAIRO Catcher MIN 467 66 9 58 3 0.309 0.389 0.442 0.830 62 82 $10 [/TABLE] Oliver is the most optimistic, again at Catcher: .300/.382/.449 with an OPS @ .832 and BABIP @ .347, AB: 523.
