total roto points each while the 5 drafted between the third and fifth round average 0.92 projected roto points each. The dropoff is slow from that point on with the 17 remaining first basemen drafted before Round 30 averaging -0.83 projected roto points.
After Prince Fielder is off the board, the pickings are slim as your best bets for value would be Kevin Youkilis or Adam Dunn right away. Then, there are a couple of choices in the mid-rounds such as Billy Butler or Carlos Lee that offer some sneaky value. And, if you're digging late, there's some nice potential for decent bench value in Michael Cuddyer, James Loney or Garrett Jones (with some young guns out there too like Freddie Freeman or Brandon Belt).
However, on the whole, this is a position that has relatively little change in value after the first five rounds. Get a good first basemen early at all costs as a result of this. If you're the odd man out somehow, don't force yourself into drafting Paul Konerko in Round 6 when you can get very similar value in Round 20. Because of how slow the decline is here, use the mid-rounds to fill up other positions then revisit 1B later on. This also applies if you're looking at this position for a corner infielder in the mid-rounds as the difference in rotisserie value between Round 6 to 22 is very small. Draft early or draft late but don't dwell on first base in the middle rounds of 2011.
