Dunn is way more valuable than Pierre as a hitter. He’s only way better than Pierre as a player if you disregard defense. Including defense Dunn is only an above average player, not a star. Here’s Pierre, Dunn, and Manny’s value in wins over replacement over the last 4 years (2005-2008) according to Fangraphs:

Pierre:
2.3
3.7
2.6
0.6
Total: 9.2

Dunn:
2.7
2.0
3.1
1.9
Total: 9.7

Manny:
3.2
3.9
1.2
6.5
Total: 14.8

A 2 win player is around average, 4 wins is an allstar, 6 wins or higher is an MVP candidate. The problem with Dunn is he gives back almost all the runs he produces with his bat in the field, while Pierre is a plus fielder. Dunn also is the type of player who tends to age very poorly. I think realistically we can expect Dunn to be worth around 1 more win than Pierre, while Manny is worth 2.5-3. While I wouldn’t be opposed to a cheap one-year deal for Dunn, I think the actual contract he receives will not be worth it for the Dodgers because he is not a huge upgrade over Pierre, despite how much Pierre annoys us all.

Spend the money on starting pitchers, where you are likely replacing replacement level innings for much of the time, meaning Pettite/Sheets could be 2 win upgrades each. They could therefore be possibly worth double the value of Dunn at a similiar price.

Dunn is just not a worthwhile risk given our teams current situation in my opinion.

want to sign for 1 year with a player option for a second to increase his stock and sign one last contract.
