This is a tough one as I usually use the same philosophy as you - play your guns no matter what. Nothing hurts more than benching a "go-to" guy to see him put up 20+. In this situation though you may want to look at it as not so much benching a go-to guy as benching the guy getting him the ball. Lindley simply could not find Fitz (or any other receiver for that matter) last week vs the JETS....it certainly worries me when he plays against a secondary like the Seahawks.
IMO Tate is your guy here. He has been putting up numbers and Russell seems to be heating up as well.
Best of luck!
