The Yanks are better off with Swisher rather than Nady

So far Cash has done a nice job getting all the pieces the Yankees need (by giving them hundreds of millions of someone else's dollars), but there is one thing irking me, barring a trade, the Yanks plan on starting Xavier Nady over Nick Swisher. While both players are relatively similar, Swisher is two years younger, switch hits, is more versatile and athletic, and plays better defense (Swish's best position is first, but still plays above average in the corners).

These are the 162 game averages for each player:

Nady
BA .280 OBP .335 SLG .458 HRs 21 RBI 78 R 69 H 150

Swisher
BA .244 OBP .354 SLG .451 HRs 28 RBI 86 R 94 H 137

They both have very similar career numbers, but Swisher has more potential to be a masher, while Nady is merely a nice 5th or 6th hitter.
