I think it's because he looked sharp in practice. It would make sense to try to bring him back to game speed ASAP, and also force other teams to prepare against him.
Most football logic would've dictated so... Miles does what he wants regardless of logic obviously. But I'll give props where it's due, he seems to be a better runner than he was last season, just hope he doesn't attempt the pitch.
I see that point and they just put Lee in for 3rd & 6 which isn't good. That is not good management of the QBs or team. I had no problem putting JJ back on or playing him as a back up or putting him in for situational reasons but to mess with chemistry like this is VERY risky.
