I don’t think the landing spots of Prince Fielder or Albert Pujols matter too much here. These guys are going to put good numbers up pretty much no matter where they go.
First base is loaded. Not many positions have more guys hitting 20 homers or more than you have teams in a standard league. Don’t look for that to change.
If your guy gets hurt, it’s the easiest position to ride hot streaks in for a replacement. What makes it so great is that banged up players are moved to first base, especially in the National League.
So, eligibility is consistently gained by good players who aren’t even first basemen. You really can’t ask for more.
Having said that, there are some guys that are clearly a step above the rest. The aforementioned duo of Pujols and Cabrera, Adrian Gonzalez, Prince Fielder, Joey Votto, even Paul Konerko are all bankable guys to be at or around .300/30/100, if not more.
If you can get your hands on those guys, great. But realize that first base is by far the deepest position in the game. If you can get your hands on a reliably stellar player at another position, particularly in the infield, don’t be afraid to pass on those guys and fill in later.
