At an Akron Open, while enjoying a match between Mark Maryo and Nick Varner, I asked a strong player named Jay Reed a question: "How do I learn by watching players who are profoundly better than me?" He told me "don't make their mistakes."
In this manner, your post is valuable. I caution you, however, to consider whether or not it is based on isolated observations of these flaws.
To say, for instance, that Danny is affected by his opponent seems short sighted to me. He is a gladiator...a champion of the road and tournament. A hall of famer and teacher to us all through his insightful commentary. Who are you to take apart his game? Did you beat him for the cash??? Was he bearing down, in his prime or setting up some backer watching him from the shadows? The big picture says more.
I'm not the official AZ protector of Danny D, or anyone's reputation other than my own, but I question your thread as possibly taking a snapshot and then applying it to a name that has held world class status earned from a lifetime of achievement.
To borrow a line from the owner of Chalky's, "Who are you, the end of the world?"
wow. talk about totally misreading the post.
