it is a funny one.
I do
trainee/trainee/and an other trainee
and make sure my guy who can foul out is not trained in last game so I can hope to fix his mins.
My last game I got
47 and 1 mins. So your plan will not work for 48mins. But now I swap the 2 around and cross my fingers it works. If one is a little short put them in behind my 3rd and less important trainee.
