It's pretty well known that coaching staffs will often travel to a couple of different other places whether it be the pros or college level every year to take cues from other coaching staffs. For example BYU's staff traveling up to Seattle to meet with Mike Holmgren and his staff this off-season.

LaVell Edwards and his staffs had coaching staffs coming in by the droves from the pro and college level for a long time. He was roundly respected by anyone and everyone having to do with the game. Well except for R.C. Slocum maybe.
