Roster percentages in daily fantasy sports are important, especially when playing in tournaments. In some sports (i.e. the volatile ones such as golf and baseball), entry percentage matters more than in other, more consistent ones (e.g. basketball).

The reason for that is -- if a popular basketball player flops, he likely still provided you with some production, unless he left the game early or gets scratched.

In baseball, an expensive option can still go 0-for-4 and burn a hole in your lineup. In golf, a missed cut from a player rostered by nearly half the field can really make the difference in tournaments.

So studying roster rates can help your DFS game, and we'll be providing them for you each week.
