Is there are reason for all the blocked punts this early in the season? There have been 5 or 6 already this year and only 8 all of last season.
Missed blocking assignments on punts?
That would be my guesses.
I agree with those reasons but due to the statistically greater total - which will result in approximately 50 blocked this year - would suggest that some underlying factor is also at work. A rule change perhaps or just coaches practising the block.
