Tampa Bay's backfield combination of Rachaad White and rookie Bucky Irving continues to produce, but figuring out which is going to have a bigger game week to week is next to impossible at this point.

Bucky Irving is breaking out, Saquon Barkley is breaking records, and Justin Jefferson is breaking hearts heading into Week 13 of the fantasy football season.

ANALYSIS: The Bucs are coming off a Week 11 bye, and their offense gets to feast on the lowly New York Giants, who rank 22nd in the NFL against the run. It's been a backfield-by-committee situation in Tampa Bay this season with Rachaad White, Bucky Irving, and Sean Tucker all seeing touches, but Irving's production stands out among the others.

Four games are in the books for Week 13 but there's still a lot of action to go in fantasy football. Here are players to start or sit this week.

There are a number of situations that can affect players' scoring outputs. For example, injuries to the player, injuries to teammates, strength of schedule, and matchup-dependent factors. All of these need to be considered when making close start-sit decisions.
