"The GMTR player rater is specifically designed to provide player ratings for head-to-head (H2H) leagues. It does this by estimating the probability that a team would win a statistical category (on a per week basis) with a specific player versus without that player. The resulting probabilities can be transformed into actual fantasy wins, represented by a measure called Wins Over Replacement Player, or WARP."
Simply add the "WARP" of all of your players, filtering for all of the games played in the season so far, and compare it to the total WARPs of your opponents' teams in your league. From there you can see a numerical visualization of how your team stacks up. That's how you can track the overall value of your players' season-to-date performances. Generally speaking, players who perform well across many categories tend to have good WARP ratings.
We're four weeks into the season and it should clear to owners what their teams' specific strengths and weaknesses are. Your team can be doing well overall, but has yet to win a rebounds or three-point shots made in any match-up. This is where category specialists come into play. These are players who may not necessarily have good WARP scores but excel in delivering valuable production in very specific categories.
In the rotisserie format, specialists can help teams that happen to be cellar dwellers in the standings of a particular category. In head-to-head daily changes leagues, these players can be added and dropped, cycled through within a week to boost specific categories that being contested during a specific matchup. So even if these players don't have great overall fantasy value, they serve a purpose on fantasy teams.
Based on totals over the last two weeks here are some players you may want to consider adding to your fantasy team to bolster specific stats. In parentheses is their percentage of ownership in Yahoo leagues.
