We had a suspicion yesterday the Chiefs' proposal to require players with long hair to tuck it inside their helmet to make sure their number and nameplate on the back of their jersey would be tabled until a later date. 
That's exactly what happened, as the NFL decided to take the matter up at their May meetings in Atlanta.
Even then, we suspect the proposal won't be adopted, especially after NFL commissioner Roger Goodell and the competition committee take up the matter with player representatives. Once Goodell said yesterday that he wanted to seek the players' input, we knew it wouldn't make sense to vote on the matter until that happened.
In the meantime, the NFL has some tricky collective bargaining issues they have to address. Too bad they weren't so simple as figuring out what to do with the players' hair.
By the way, the issue came up in one of the comments about whether it was a penalty to tackle a player by his hair. Answer: It's perfectly legal. It's considered a part of the body, and no penalty is called.
