I can see why some would want Foye/Burks at PG instead of Tinsley, but consistency is going to suffer greatly for the 2nd unit if that happens. I would predict the 2nd unit offense would have games were it was just ugly basketball all the time. I think Tinsley brings a calming effect to the 2nd unit that is usually needed.
I would be interested in trying it out though just to see what happens. I would assume it would work some games, but I would also think we would have a lot more quick shots and just flat out wasted possessions.
