I get the logic behind the positional adjustment and I don't take fault with that necessarily. Well I do a little bit, it overrates bad players who play premium positions and underrates first baseman defense generally -- but that's not really my point here, I'm more so critiquing what they give precedence to or ignore when making the calculation. I think Vaughn is a better defensive first baseman, relative to other first basemen, than dWAR calculations gives him credit for. I can't prove it quantitatively, it's just the eye test, he's saved some really god awful throws and turned them into outs. There was a play the other day, I forget who fielded it on the left side of the infield, maybe Mendick, it was a tough, close play but the throw was offline and in the dirt. Vaughn looked like a 200 pound ballerina, I don't know how he contorted his body to make the scoop. I'm exaggerating a little bit but I'm generally impressed with his play at first base; he's missed some hard grounders he probably should've fielded which I think is what's counting against him, but I bet he's saved a couple of runs making catches that other first basemen wouldn't get to (see: Michael Busch. literally the worst first baseman I've ever seen...I'd still rather have him than Vaughn).
