true. good points.
lol, i once had a combination of your first part (bad enough) plus low stamina. it was actually a surprise if he didn't get subbed out for a minute or two! a pretty consistent 45-47 minutes each game. (which sucked, since i could only get away with using him in cup games / scrimmages)
kind of related, i loved the times i'd be training a guy at PG & the coach would randomly move him to SG for a minute or 2 in the 4th quarter & move the SG to PG. (no substitution, just position swap). i guess that kind of fits in with the first part of what you wrote though.
I didn't get that particular swap a lot. What I do get, though, is the case where my trainee at PG fouls out and despite having a perfectly good guard on the bench (who is backing up SF or SG), the coach instead decides to put in a PF/C who is backing up a big man.
