It's pretty common to break a Detroit when a shaft lets go, so that's not unusual at all.
Overall I think breaking a 14FF shaft first is a fluke, so I wouldn't start thinking that 10-bolts and 208's are bulletproof or anything. I would say that 99% of the time the 14FF would NOT be the first to break, but under the right circumstances obviously it can. As already mentioned fatigue, bent housing, manufacturing flaw, or just the right circumstance could have made it fail. Wedge a rear tire down in the rocks and try to power out of it and boom.
