When Brendan Shanahan went public with his thoughts on why the NHL wanted to test possible rule changes and modifications over a two-day camp this summer, he assured that radical change wasn't on the agenda because the NHL game already is in good shape. You couldn't hear any dissent from any of the GMs who attended the Research, Development and Orientation Camp Fueled By G Series on Wednesday and Thursday. The majority is thinking about at least some potential changes, but the key word here is subtle, because the last thing the GMs want to do is confuse the fans.
