It's not much compliment to pay oh you lost but at least you didn't have a mental break down. You could even deal with his mental outbursts ( ala Mcenroe) it the results were there to back it up.
The problem is when Ryan loses mental control (has tantrums, rants, swearing jags) he starts playing worse and signals his opponent to go in for the kill, which is holding down his win/loss ratio. After two years on the tour he's got a reputation for tantrums/brattiness, receives several conduct fines every year, is losing fans and potential endorsers who find his behavior unattractive and unwanted regardless of the results. Especially if he reaches the top ten, it'd be horrible to have to endure another decade of the top seeded American as a reincarnation of bratty, ill-mannered McEnroe or Roddick.
He knows this as his new year's resolution for 2012 was to receive no conduct fines, which he's managed to avoid so far, but gotten warnings and had to make a public apology for his meltdowns at the Olympics while representing the US.
So the post was to compliment him on doing a good job today under trying circumstances (he looked ready to erupt a few times) on a goal that he, his team, and fans see as essential for his continued rise in the rankings and broad appeal.
