Being there and watching the match it was very dissapointing. He lost complete concentration after winning the 2 first sets. Almost as if he thought he had already won. And when then Bjorkman stepped up his game, Luczak seemed to find it hard to find his focus again. But this is what it is all about, getting to play these big matches and getting used to 5 setters and playing the big arenas. Give it a few more months and I think we can see luczak doing some damage on the ATP tour and not only at challenger level.
He said he already thought about being in the 2nd round before finishing the job and then it was too late for him. He has played enough big matches and 5 setters at the Aus Open, but he is too nice on court sometimes and has failed to take chances when they have been on offer.
I have watched enough of Luczak to know what the main problems with his game are. I think you are overrating him saying he can do damage on the tour level, he can win some matches, but damage isn't something he is capable of. His main goal will be top 100 at the end of the year and he should be able to achieve this barring injury or illness.
