You forgot “allow hitting”
I always thought golf need outside linebackers rushing the putter!
Less hitting, more actual tackling.
The standard of tackling in the NFL is poor, they could learn greatly from rugby, where equally huge men tackle at equally high speed, but do it far better. Brutal, and less flashy.
Too many ‘primetime hits’ in the NFL, I have read college and NFL coaches of 30-50 yrs exp., say the standard is getting worse.
