The Raiders are really going to need Reece on Sunday. The Chiefs are rushing the passer with great efficiency and using Reece as a safety valve is going to be a necessary part of OAK's offense. Rashad Jennings is also banged up with a hamstring injury and Darren McFadden is up to his usual tricks of missing games.
On paper, it makes a lot of sense to use Reece. he's an adept pass catcher and the Raiders really need to go everything they can to offset the vicious pass rush of the Chiefs.
Fantasy impact: KC is probably going to shut down the Raiders offense, so there really isn't much allure to using Reece in even a desperate situation. The Chiefs have shut down a lot better teams than the Raiders, so there's not a lot of allure to playing Reece this week. He belongs on benches and he's far from a must-own player.
