RG3 hasn't "started to look good throwing the ball," he is a good passer. 66% last year with over 8 yards per attempt and only 5 ints. You put way too much stock in watching games early in the year when he was playing on one leg.
Either way, our interior O-line is pathetic. He was getting hit before he could even get back in his drop. I've never seen so many defensive tackles get sacks and pressures on a QB as I've seen the last 3-4 games. If he's not getting sacked, he still has no pocket to step up into and make a throw. The 2 guards and center for some reason, just dropped off a cliff this year.
