How do you rank the "iron man" streaks of these 3?

Some might say the streaks were counterproductive when it would have been best during certain times to rest your body if you were tired and struggling, but that's a whole other argument.

Just in itself, which do you think is the most difficult?

297 straight starts in a violent sport like football? (Jim Marshall's 270 ain't too shabby either, that guy is arguably HOF worthy and all anyone remembers is him running the wrong way, 1,192 in basketball, or 2,632 in baseball?

The 32 year old virgin also got a couple teeth knocked out on a dirty play in 1996 by J.R. Reid. They just kept his streak going afterwards by having him enter and play a minute or 2 by leaving.
