That looks pretty good to me. Pujols and Helton are definately first and second but from there it gets a little tough. Overall, I think I'm more bullish on Delgado than most fantasy owners. He was a monster in 2003 and the second half of 2004.
I would wait to see where he ends up. If he goes to a good team with a good hitters park, I might rank him as high as #3 for 1B. On the other hand, if he goes to a good pitchers park and/or a team that's not gonna put guys on base, he'll slide down the rankings.
In the interests of full disclosure, Delgado is one of my keepers so I may be biased. But I kept him for a reason.
