I've argued this in other places as well. Sure, getting a snake eyes gives you a turnover. But the odds of a snake eye are pretty low. The odds of surviving an 8 turn grind without turnovers are higher, I'd wager, especially when you have to reposition the cage every turn. I often see players make several risky dodges and/or GFIs to score on their "safe" running drive where a simple throw/catch with pass+catch would have been far safer. I assume that's what's being referred to. If at any point you're rolling more than one d6 that have to succeed (dodge, gfi, 1d blocks, etc.) in order to score your TD (especially if you're out of rerolls!), you're equaling your pass/catch risk.
