With news coming out on Monday that Chris Johnson suffered a fractured tibia and Andre Ellington is dealing with turf toe, David Johnson rockets to the top of the waiver wire priority list. He saw eight carries against the 49ers, with most of them coming after the veterans went down. Johnson is an explosive athlete who is at his most dangerous when catching passes out of the backfield. Aside from Johnson, the Cardinals have Stepfan Taylor on the roster and Kerwynn Williams on the practice squad. Taylor could see some touches, but Johnson figures to get the bulk of the work against the Rams next week. CJ2K's injury could keep him out an extended period, and Ellignton's is of the lingering nature, meaning the rookie out of Northern Iowa could be in line for a massive workload down the stretch. If Johnson is on the waiver wire in your league this week, do everything you can to get him. FAAB Suggestion: 90-100 percent.
