Concerning your Brutus Buckeye Team I think that Hanada and Fugunaga must be your priority cause of their potentials.
Others will follow the same training program at least at the beginning. They have very different profile.
You must also define the reasonable objective profile you want to achieve. I'd rather lean towards a PF profile with for simplicity, Hanada's TSP=135 (75+60) and Fugunaga TSP=125 (70+55)
I did some simulations, There are several possibilities, in my opinion the most profitable and the traditional solution is to start with 1 on 1 SF/PF until the end of the season cause you can train up to 6 players (your 4 + Iseki + another one).
2nd solution, Starting with the ID but it's a risk to loose 4 or 5 pops over the first 2-3 seasons which, as everyone knows, are the most prolific in pops, and you could train only 3 players.
But at the final, both solutions will give similar profiles .
A 3rd solution would be to mix a little ID for C with a majority of 1 on 1 SF/PF, but you can only train 3 players on single-player sessions.
Depending on your choice, I can make you a training plan over several seasons, It can be corrected depending on the pops.
