We tripped one once in 2006.
We had the four drive CIMs, and the big CIM, and the compressor and a pair of FPs running non-stop through 4 pretty darn close to back-to-back elimination matches. There was lots of pushing and shoving, plus our "ramp wiggle" to get into position involved "walking" the robot by cocking it and then running it into the drivers station over and over (which kept the CIMs fairly close to stall)
It actually took us a couple of minutes to find the problem, we didn't think it was possible to pop it under regular robot use!
OP, I've seen more than 9 motors on an FRC robot. I think you're okay.
