I picked Molina up off the Waiver Wire to replace Mauer until he came back. Since I also lost Devine, I was able to keep Molina as my DH (swapping Mauer & Devine on my DL). I now have to look at dropping someone or doing a 2-1 trade to activate A-Rod, and have been shopping Molina around. Let me tell you - there are NO buyers of Molina. Sure he's batting cleanup, but here are the knocks on him:
#1 - Average is great, but it's May and he hasn't drawn a single walk. Not one. In fact he's a rare player that his Average is actually HIGHER than his On Base Percentage (due to sac flys). He is an incredible contact hitter (iirr 522 ABs last year with 37Ks and only 10 walks?) but in leagues that use OBP instead of average, he is pretty pathetic.
#2 - Low Ceiling. You posted the numbers already. Not on the right side of 30 (he's 35) and he'll deliver 15-20 homers, .275-.295 average, and 80-100 RBIs. In this lineup, probably 50 runs. Last year he delivered that, and although RBIs was tops at the Catcher position, due to his low OBP, SLG, no SB, and terrible runs scored, it was good enough for only 6th fantasy rank. That is with players like Chris Ianetta only playing partial seasons.
#3 - Risk - Sure he's been consistent, but he's 35 and playing EVERY DAY behind the plate. As fantasy owners, we'll ride that as long as we can. But he's played 386 games over the past 3 years at C and I'll bet that's more than any other catcher in the Majors. That's likely to put wear and tear on the body, so is an injury risk. Anyone you try to trade him to will factor that in.
So... looking at the catchers that people may value more than Molina:
Mauer, Martin, McCann, Martinez - these are the elites.
Iannetta, Sandoval, Saltalamacchia, Wieters - these are the top tier prospects
Then you get into the "Steady Eadies" of the catchers:
Molina, Posada, Napoli...
And the breakout candidate of Inge.
Certainly Molina is worth a roster spot, but you're not going get much for him, given that those players listed above are all likely on a roster... and who wants to carry two catchers, or use a Catcher as a DH?
