I'd like to chime in on the "stamina" and by reference, conditioning, issue.
What the St. John's game showed is that against a veteran, older, physical team, Bailey cannot play 37 minutes and not be very tired at the end of the game - and that Harper was also tired with 33 minutes in that game. One of the things Pikiell said before the game was that he was going to be trying different line-up combos, and roles.
It seemed obvious - and you saw it in the Monmouth game, the 1st real game both Harper and Bailey were available - that Pikiell was both still working on his rotation, and would find a way to enhance the chance Bailey and Harper were strong at the end of games.
I made a projection, prior to the Monmouth game, which came to pass in that game, that barring injury or foul trouble, Harper and Bailey would play (i.e. be n the court) the 1st 4-6 minutes of each half together, and in any closer game also be on the court together the last 4 minutes of the game - and maybe of each half ... but IN BETWEEN, Pikiell would never have a stretch where BOTH Harper and Bailey were off the floor. In other words, during the middle parts of each half, Pikiell would get each of Harper and Bailey their rest while the other was on the floor.
And that is exactly what happened in the Monmouth game - though Bailey did not play the last 4 minutes of the game because of cramps (a conditioning and hydration issue). And this is what is going to happen throughout the season. I DO expect each to get 32+ minutes per game in any close game.
