Sorry if this belongs in another sub-forum, but Football 101 was the one I thought most logical.

The best thing I can say about this rule is it's not exclusive to RBs, like the rules against hitting QBs or receivers above the shoulders or below the knees (indeed, many feel runners will get hit below the knees more often BECAUSE of this rule.) Nor is it like the rule against hitting a "defenseless player," which mandates WRs be allowed to make receptions and start running before contact, while hitting a RB as he takes a handoff is still just a great fumble-causing play. Since passers and receivers get hit so much more and harder than runners, they need extra protection.
I'm SO glad the NFL is taking further action to reduce the advantages of runners over passers and receivers in a league so increasingly dominated by running passing might otherwise have disappeared altogether. It's deplorable the physical punishment QBs and WRs endure makes it impossible for the bodies of guys like Favre, Peyton Manning and Elway to sustain the decade or more of Pro Bowl level play guys like Grange, Thorpe, Sayers and Terrell Davis enjoyed. Speaking of enjoyment, it's also good to know the NFL is fixing the rules to avert the risk of one-dimensional offense. Kudoes to Goodell on another typically good job.
Perhaps the best news is for Jake Plummer: Having left football for handball because he felt it a game that can be played all ones life, he could return to the NFL once it completes gradual transition to that sport.
