Week 3 role changes

Each share is this week's, set against his usual: his average over his previous four games with the same team (fewer early in the season; the row's details say how many). To count as a riser, he has to reach a real share this week: half his team's snaps, 15% of its targets (10% for a back), a fifth of its air yards or a quarter of its carries (quarterback runs included). A faller has to have had one. A player who did not play is not a faller. His status is on his page.

Largest move is measured against each share's own bar, so moves in different shares rank together: a 7-point move in target share counts the same as a 10-point move in snaps or a 12-point move in carries or air yards. The bar under each move shows that size.

The kinds. Most big moves in a week are one injury seen from both sides. A rise is filling in when a teammate at the same position, who played in the team's previous game, sat or played under 35% of snaps after usually playing at least half. He has inherited a role that lasts only as long as the absence, so the row says where that teammate stands. A fall is hurt or left early when the player is on the injury report (going into his next game, for a past week) or played under 35% of snaps. That doesn't count as a lost role. The rest are growing and losing roles.
