The Arizona Cardinals had 84 offensive snaps against the St. Louis Rams. Normally the workload is fairly evenly divided at running back. On Sunday, it wasn't, which has traditionally been the case for a Bruce Arians offense. Rookie running back David Johnson played a whole bunch.
Let's look at the snap counts for each position.
Quarterback: Carson Palmer, 75; Drew Stanton, 9
This was the perfect way to get Drew Stanton a few snaps. The Cardinals had a big lead and Palmer could take a few plays off at the end.
Running back: David Johnson, 59; Kerwynn Williams, 14; Stepfan Taylor, 12
Not much sharing of snaps here. David Johnson got the work early and Williams played late as the fresh legs in the fourth quarter.
Wide receiver: Larry Fitzgerald, 72; John Brown, 65; Michael Floyd, 52; Jaron Brown, 20; J.J. Nelson, 12
Once again, Michael Floyd is the number three guy, either because of injury or because John Brown is the guy playing better. In any case, the receivers all played well. Even the guy with the least snaps had a touchdown.
Tight end: Darren Fells, 53; Jermaine Gresham, 47; Troy Niklas, 14
Fells played more because Gresham left with an injury.
Offensive line: Bobby Massie, 84; Ted Larsen, 84; Lyle Sendlein, 79; Mike Iupati, 75; Jared Veldheer, 75; Jonathan Cooper, 9; Bradley Sowell, 9; A.Q. Shipley, 5
Veldheer and Iupati left the game when Palmer did. Sendein left a few plays later.
