It may come off as odd to say this, as a purveyor of the best draft tool around, but draft tools can't do everything. One of the great subtleties to drafting in fantasy baseball is seeing and exploiting tiers within each position. While the Big Board will help you see them, it's another thing to plan for them and make sure you avoid the biggest drop-offs in each position on draft day.

After calculating player values and ranking them, you'd like to think you could just always draft the best available remaining player... but if there were 4 great players and 8 terrible ones at a given position in a 12 team league, you would want to make sure you're one of the 4, not one of the 8. This is one of the main weaknesses of using Replacement Levels to calculate player values. And on top of that, if you can get the 4th of the four good ones, you'll be able to spend time on other positions earlier in the draft without giving up much.

This is illustrated pretty well at C this year: Sanchez and Realmuto are an obvious top-2 of similar value, and are followed by gap before the next tier which contains Ramos, Contreras, Posey, Grandal, and Molina. After that, there is basically nothing above replacement level. It's a great argument for taking a C in the mid-rounds, before those top seven are gone. Conversely, if you don't get one of them, just chill out, don't panic and grab one of the crappy remaining guys immediately. If I don't get one of the top-7, I'll probably settle for a last-round catcher, or 2nd-to-last if I really have a favorite sleeper I’m targeting.

Users of the Big Board will have seen this already, but using the default Big Board custom projections, the distribution of player values looks like this for a standard 5x5 ESPN league:
