Technique and route running. Said he essentially taught very little but encouraged a lot. Said he learned next to nothing from Holliday. I was surprised and taken aback. Could be personality but it was a bit surprising to hear that.
Btw I love Holliday. Think he's a great guy and have met him.
Nothing against Holliday. I only share to defend Cahoon from those who are frustrated with results so far yet don't know anything at all about what is happening behind the scenes.
