The glorious exchange for your entertainment: Law: Very, very slight preference for Mills, because we already know what Mathis is, but Mills still could improve enough to have value. Comrade Lyle: @keithlaw Mathis is respected and valued only by every pitcher with whom he has worked. No analytics for that. Law: And is terrible at everything that matters. RT @LyleMSpencer: Mathis is respected and valued only by every pitcher with whom he has worked. Comrade Lyle: @keithlaw Mathis is respected and valued only by every pitcher with whom he has worked. No analytics for that. Law: That's good, since Mathis doesn't help anyone win anything. RT @LyleMSpencer: @keithlaw Winning doesn't matter. Comrade Lyle: @keithlaw Winning doesn't matter. Won 12 more than Napoli in exact number starts for four years together. Nap caught Lacker, Weaver more Law: @LyleMSpencer CERA was demonstrated at least ten years ago to have no utility in evaluating catchers. None. Comrade Lyle: Catching same staff, Mathis had CERA .88 -- almost a full run -- better than Napoli for four years. Won 59% of games he started. Law: @LyleMSpencer Besides, you said there were "no analytics" for what Mathis gives, then you quote CERA. Which is it? Comrade Lyle: Numbers guys hate Jeff Mathis. Teammates love him. I think Mathis will settle for that tradeoff.#angels Comrade Lyle: CERA is of definite value when evaluating catchers handling the same pitchers over a number of years. I don't care what your crowd says. Comrade Lyle: @keithlaw Love analytics. Still have my Bill James Baseball Abstracts from '80s. Neyer, Dewan, James have Mathis 1-2-2 among def. Cs. ------- Law then ignores the ramblings of a blathering idiot trained in the propaganda tactics of the Soviet Union and tweets about food. Seriously though, this exchange summarizes how ridiculous Comrade Lyle Spencer is.
