My spin on it is that Les Miles takes very seriously the commitments he makes to players when he recruits them. Players commit to LSU for 4 years and Miles makes a commitment right back to those players. I don't know this for a fact and it might simply be a commitment Miles makes to himself to take care of these players and give them every opportunity to succeed. Right now the 2 QB thing is working well. Playing both appears to be taking the pressure off of each one of them and is allowing them both to feel comfortable. Maybe it is just me, but I don't attribute the fact that JJ is the starter to Miles being pigheaded or stubborn.
I think most of us would agree that CLM is not an X&O's genius (don't even get me started on clock mgt), but I really feel that he is dialed in to his players mentality. And from what I've read and heard the players like him and enjoy playing for him. I personally have no idea what goes on in practice, meetings and film study, but maybe (just maybe) bringing JL along at this pace is what's best for him. One thing I do know is that for the first time in several weeks I can't wait to be in Tiger Stadium Saturday to see what unfolds.
Then what about Miles commitment to JLee? The problem with going down this path that you're suggesting is that if that were the case Miles would have made a commitment to every player on the team. Why is JJ's commitment worth more than JLee's commitment? If Miles is as upstanding a person as he's made out to be the answer is: It isn't. Then the question arises why would Miles start JJ over JLee? There's only 1 answer to that question and it has nothing to do with a commitment. Miles thinks it's whats best for the team. Now we can argue whether he's making the right decision or not. However I don't think a "commitment" is the reason he's been starting JJ. Miles also has a commitment to the school, it's fans, and his own players to start and play the person that gives them the best chance of winning. And that commitment comes with a 4 million dollar contract.
The threat of the pass is more effective than JJ's lack of executing the read option as lsutiga so duly noted. So there you have it. Lee is great for this offense all around. JJ appears to be relegated to just a specialist in short yardage and goal line situations, if you ask me.
If Jordan Jefferson is so emotionally fragile he can't take being sat down for poor play, that just triply confirms he should not be the quarterback of this football team. You put the player on the field that gives LSU the best chance to win. Period. I think Jarrett Lee taking 90% plus of the snaps from center is what accomplishes that goal. Miles and Crowton, for whatever reason, don't see it that way. Fine. I'll defer to them, they are the coaches after all. That said, I would not be surprised in the least to see Lee's role in the offense continue to grow and Jefferson's continue to decline, especially if Jefferson's passing abilities and recent propensity to turn the ball over don't improve. If it's all about how they look in practice, I would hope what Lee just pulled off down in Florida gives him a huge personal boost and he has a lights-out week of practice, if that's the only thing stopping Miles/Crowton from completely handing the keys to the offense over to him.
