Another tough scenario. I would probably play Murray with 2 fouls before I'd play Garza with 2, so I'd probably keep Murray in and go zone or have the double come sooner on post entry so that it's less likely he would get a 3rd foul.
Another option is just to have Fran go off on Bo Boroski and get a T just to chew up 2 or 3 minutes until Garza is rested

. I've seen coaches "accidentally" spill water on the court for this purpose, or perhaps a guy get injured, that type of stuff. Somewhat unethical unless you consider gamesmanship like that fair play, but if we're playing Illinois I'm ok with it!
