Its far more likely to miss a 43 yard FG than have a punt blocked, especially in max protect. If you miss the FG, they get the ball at the spot- the 40. So they only need like 30 yards to be in FG range. Odds of a blocked punt when you are in max protect are very low and there really should be no return when punting from the 35. It either goes into the end zone or is so high as to be unreturnable. Anyway, that's my view on it.
