Contracts (oh yes, foolishly) are about what you have done, and not what you will do. I give you the season preceding Mauer's contract: .365/.444/.587/1.031 171 (OPS+) 7.8/6.2 (BR/FG WAR) Mauer's career wOBA (.373) would be good for 23rd in the entire league this season. So just by his bat, he'd be the 23rd best DH, even including this awful year. The whole trade-value series is silly in that it absolves itself of long-term commitment. Ask Dave Cameron how long he's willing to commit to any of his trade value contracts. Year to year analysis of player worth is easy and obvious; the commitment of years and dollars is tricky. Honestly, a teenager could sort player salaries by highest per annum and see players like Mauer, Prince, Verlander, Pujols, Rodriguez (Ha!) are bad value (in terms of very recent data, so recent we tend ignore sample size in such studies, well, for convenience). As much as Dave Cameron would like to pretend that these players don't (or rather shouldn't) have market value, he's not only picking his prey, he's wrong. Prince netted Kinsler and cash. Mauer and Verlander and Pujols were killer studs so recent that teams will absolutely risk value. Cameron seems to eschew the necessary (even personal) risk GMs take in acquiring talent. Suddenly, two years after Pujols signs his contract, the Angels contend; part of why they can't trade him is that they need him, and they count themselves as one less destination. The whole series favors players who have zero trade value beacause it'd be absolutely foolish to trade them OR players who zero value because their value is anchored so much to their current situation. It's silly.
