"A rollback would impact virtually every golfer, not just the very best players, so we have no plans to roll back either."

There's a new Golf Magazine Q&A with the USGA's Dick Rugge who confirms that a rollback isn't on the radar but offers this in response to a question about future rollback scenarios:

Rugge: If it were determined that the game could be improved by implementing an equipment rollback. For example, if driving distance once again began to increase significantly, there may be a need to consider changes to the rules governing clubs or balls. It’s purely hypothetical, but there could also come a time when environmental issues place such significant burdens on building or maintaining golf courses that reducing distance could become a necessity.

Haven't we reached that point?
