I thought it looked more like miscommunication than bad throws. The way Malik has looked, it seems more likely that Richards is the one who isn't on the right page.
Coming into the season our top two offensive players by far were Walton and AR. Walton without a meaningful carry the whole year, AR a shell of his former self. Still undefeated, getting better, and rolling the #3 ranked team by 5 tds.
I'd argue without catching a single pass he's still a huge part of our offense. Every defense coordinator still respects him and he opens it up for other WR's to shine.
I got a feeling Richt has a trick up his sleeve regarding Richards (maybe throw him in the slow unexpectedly) he's gonna pull at the right time.
Richards is still blocking his a$$ off. Dude is still nursing the hamstring/ankle its clear he can't plant and change directions right now that's really impacting his route running.
