I think that's what is best for Jalen too. He graduates next Dec. He could transfer to the school of choice next January and go thru their spring ball and have 2 years to play for them IF he redshirts at Bama next year.Regardless as to what JH decides to do, transferring before the fall would be silly - not only because he loses the chance to play if there's an injury but also because he's on track to graduate this coming year, so he can stay with the team and gain all the knowledge, training, etc that's available to him - FOR FREE - then transfer an play immediately as a grad transfer. If he transfers over the summer, according to the rules, he sits a year...
Unless I'm missing something, the intelligent (read - not driven by emotion) choice is to stay at Bama through the 2018 season.
All of this assumes he's not the starter. Saban has made some interesting personnel choices over the years, so I'm not certain JH won't be the starter against UL.
The details are in the "IF." Part of the loyalty CNS might have to Jalen is if he feels comfortable enough with Mac Jones as the #2, that he might allow Jalen to use his redshirt year and save himself sitting out after transfering. I kinda doubt this will happen, but it would be to Jalen's advantage if it did, assuming he accepts he's been passed up and will not play this fall as the starter.
