RE: Staff
Honestly, I've not had any success at all doing single-position training. I once had a superior trainer that I was paying $70K a week for with an MVP caliber prospect, and for 3 months I got 2 bumps doing single position training by the book. Complete and total waste of time, resources and energy. I could have gotten close to 70 bumps on my entire roster with a minimal trainer doing 2 or 3 position training using things like 1on1, FT, and rebounding.
It's rare I even try single-position training, unless I have been training say ID for a number of weeks and I suspect a couple of my bigs are close to a bump. But as I start re-investing in stronger trainers, I'll start being more selective in who, what and how many I train at various times.
