Wait, Cody Green didn't get the Tim Tebow treatment as a freshman. He played in garbage time and then wasn't he abruptly given the starting job? That lasted about one series into his second game, and he rode the pine the rest of the way.
The next year, they did this thing where Green got a couple of series early in games. Whether by luck or design, it always seemed to be Green backed up inside his 2-yard line in the 2nd quarter, again yanked at the first mistake (to be fair, he had many turnovers). I suppose it didn't help the dynamic that he was a sophomore, while the new starter was a freshman.
So...all told, I'm good for a traditional feet-wet kind of year for the #2 guy. Extended looks in garbage time and maybe another opportunity here or there, but in any case you want to manage it carefully. On-field experience even in limited amounts can help springboard him for 2017. A redshirt could benefit him, too. In any case, there's a lot less pressure this year on POB than on Green unless Tommy somehow loses the job.
