You can assign well sub players and still there is nothing guaranteed.
(http://www.buzzerbeater.com/match/26583723/reportmatch.as...)This substitution (Portocarrero for Capela on PG) is one of most ridiculous I have ever seen on BB. Does it have any sense to boost lineup at 1:07 before the end while leading 99-32?
My suggestions are:
Suggestion 1)
"Strictly follow depth chart" should be really strictly even in last 2 minutes or at least should be strictly in last 2 minutes if there is 20+(?) points difference. In close games I have nothing against this non-wanted substitutions.
Suggestion 2)
I can imagine split this option to two:
A) "Strictly follow depth chart" - strictly for whole 48 minutes
B) "Strictly follow depth chart (except for last 2 minutes)" - behaviour as present option
I can imagine option A) can cause drop in Fan Survey if it's used and team loses the close game.
I think even without these substitution situations training would be very challanging. Because training for example passing for PF/C, inside def. for PG/SG etc. is still very challanging even if you swap positions in defence.
