Cruize

Anyone can benefit. Hits on backs and receivers are in the blink of an eye. How the guy who hit Olave wasn't flagged is beyond ridiculous. I like the college rule. They at least review it.

Anyone can benefit from a safety perspective. From a strategy perspective there are some significant disadvantages as certain positions I believe. A cornerback would not want to draw more attention from refs, and a larger helmet could cause them to contract receivers earlier, move their head more when they do, and get more PI's called against them. A running back could find it harder to slip through a narrow gap leading with a wider helmet, and if they use their helmet as a battering ram at the goal line, they may find a padded battering ram less effective. Likewise a defensive lineman bull rushing the oline may find that a softer but less smooth helmet doesn't help them slip past the oline, and makes them more visible in the QB and other olines peripheral vision. For a receiver I see the most strategic positives outside the safety element.
