The way i look it at is who did they beat, don't like Dake but over the 4 years he beat the following future world team members - Reece, Frank and David off the top of my head that is pretty impressive
Cael #1 A thru Z
Dake is #2 because of your point about level of competition.
Smith #3
Stiebler #4 (I'd also have some 3xers ahead of him but that wasnt the question)
Dake's list of championship victims
