I'm going to make a prediction: If LJ becomes the starter this year, barring injury, he will be QB1 for the duration of his career at GT.
I think CPJ's hint that Taquan may move to AB is a clear sign that he isn't long for QB, and he's keeping the seat warm for one of the freshmen...and it's beginning to look like LJ, despite all the sizzling comments about JJ. When CPJ said "JJ will be a very good QB in a year or two" that was telling to me. You can be a very good QB, but if the guy in front of you is QB1 and playing exceptionally, you can still be very good but not be QB1. Ask Steve Young about Joe Montana. The bigger picture is JJ just isn't ready right now, and by the time he is ready, LJ just might have a stranglehold on the position. Being good in a year or two doesn't help right now, and the more reps LJ gets, the harder it will be for JJ to catch up.
As for MJ...I'm not sure what it means for him anymore. I think CPJ would like MJ to be the starter because he has a lot of experience, and I don't think CPJ wants to push the young QBs too far to fast, but MJ's health and rusty performance is making it harder for CPJ to keep the rains on the younger guys. I think Taquan's development is welcome sight for CPJ, but as I said above, if you have long term plans for someone, you're not repeatedly dropping hints that they could move somewhere.
This is easily one of the most fascinating and interesting position battles at GT in quite some time.
