Important Week 9 metrics

Running back snap rate

No stat correlates more closely with Fantasy scoring at the RB position than snap rate.

Running back route involvement

A player's route involvement rate simply represents the percentage of the team's total dropbacks on which that player ran a route. So, the running backs listed above all have run a route on at least 59 percent of their team's dropbacks. Running routes is the first step towards drawing targets, which is key to unlocking Fantasy upside at the RB position.

30% target share, 30% air yard share

These receivers have shown a unique ability to dominate both the target and air yardage share.

Target per route run rate

Target per route run (TPRR) rate is one of the most important stats available for evaluating pass-catchers in Fantasy. I wrote about it in more detail here, if you are unfamiliar with the stat.

Air yards

Tight end target per route run rate

These tight ends are being targeted at the highest rate when allowed to run routes, but that's only part of the equation when evaluating tight ends for Fantasy purposes. Understanding how often each tight end's offense allows them to actually run routes is another important piece of the puzzle.
