The problem with letting RG3 run free is that he's brittle. When he ran free in '12, he was awesome, but he kept taking hits, and it's what got his knee destroyed in the Ravens game. After that season, it was all about converting him into a pocket passer so that he wouldn't take hits.
In hindsight, that was the most stupid decision we've made in a long time, considering our offensive line's latest major signing is an overpaid, overwhelmingly underwhelming Browns guard and a washed up Ravens reject. The coaches designed the offense to be pocket passing, and with no place to run, all our QBs were hammered. Griffin held onto the ball like he would if he was told to scramble, so he put up ugly sack numbers. Kirk gunned the ball away as fast as he could and paid for it in interceptions. Colt sort of sucked the least, but that isn't saying much. He's basically what we hoped Kirk would be when we first drafted him: A solid backup who could manage a game or two.
If Griffin went to the Eagles or another team, and they're willing to cater to his skills, he'd thrive there. In Washington, we paid such a huge price to get him that him "risking injury" by scrambling turned into an unpopular strategy, and anything resembling it is lashed out at by fans. On other teams, you don't have that burden to keep the toy clean and shiny, so I wouldn't be surprised to see him do well. He also wouldn't have to deal with fans bashing his every move 24/7. (I mean, seriously, people called him a diva for talking too much. When he shut up and wouldn't talk to reporters, those same people said he's pouting and doesn't talk enough
.)
Anyway, I digress. I suppose Foles might not have kept the magic of 2013, but I'd still hold onto him. The free agent crop looks weak, and none of the rookies seem like they're surefire successes, and if you don't have SOMEONE, then you're going to be in quite a fix. For better or for worse, RG3 looks like he's going to be staying in Washington this season.
