Good to see the happy Nole fam.
I checked the score at 5:30 am and saw Nole won easily. I hope now I don't have to start out on a cross country trip every time he loses a set.
I agree that Nole has lapses in concentration (everyone does -- question is how soon can the player get concentration back) but I think he has done better since 2011 in limiting the damage. He used to lose concentration and lose the match. I think opponents counted on that. Now he gets back in the grove much better and doesn't let it prey on his mind.
