He'd be a fool to do it with 4 and less than 5. We could easily change a silent count trigger and get a 1st down.
For 4 > 5- he'd be dumb to do it on long FGs - as any penalty would make a 2nd attempt easier.
For those other cases - I was shocked that the OL didn't pop up and clip his feet (on the 2nd attempt). As the Rams (Bates?) did it vs. the Giants (and the Niners) - it's now getting to be old news. The announcers were saying - "OMG, I've never seen that before...." they just may not watch ESPN.
I don't trust that Slocum will have them ready though... Fire that idiot.
