I asume you mean the USGA Green Section presentations at GCSAA in San Diego? If so, could you specify which speakers, as there were many.
Interestingly, at the GCSAA panel on Major Tournament Set Ups, Rees Jones said the most effective way to protect the integrity of course design, stratregy and par was to have more contour. He didn't talk much about green speeds, but in any case, the emphasis on the ground game was interesting - even if it isn't clear he practices what he preached..
