And I suppose it's a very, very minor practical issue if you're a new team having to scout a bot.
It is a very, very minor point, because all you have to do is sort their roster by salary and the top 5 players are the starting 5, in PG-SG-SF-PF-C order.
if (team is bot) then (delete three random players)
I think the offseason process is server-heavy enough without having to delete players off the many computerised rosters, when this can just as easily be done when a new team joins.
