Jenkins was active against the run, clamped down in coverage at all three levels, and delivered the plays that needed to be made when his number was called.

Chicago will bring another physical run game to Lincoln Financial Field on Sunday, and with all of their trick plays and gadgets and option run game concepts, this will be a mental test as well. Sunday's win over Buffalo is an excellent springboard for this unit to jump off in preparation for the Bears.
