The idea that anyone thought they’d volunteer the 99.99999999% of practice no one outside of the team has seen is silly. I’m sure things are “leaked” or some “off the record” conversations happen, but again, doubt the real story is being told.
If you were a tight lipped coach, you’d say “it’s a real competition. It’s 50/50. No one has taken the job. Etc etc.”
That makes Miami prepare for a pocket and mobile QB. That makes the team respect that you told them it was a real competition and you’re following through. That keeps both QB’s engaged in a season where we probably will need both of them at some point.
