Do you remember exactly how those matches developed? Legenda was on a very heavy schedule and made 3 finals in a row (Metz, Vienna and Madrid). He was visibly running out of gas after the first two sets against Nadull. While he still had fuel in the tank, he schooled Nadull. He had some chances at the fifth even clearly tired. Then Paris was a bit different. There I think he choked a bit, considering he was the favorite and had came back from a 0/2 deficit. He had all the momentum and lost his concentration to let Berdych win.
The Miami final was a bit hectic but both players displayed good form and Federer was on a much higher level then. That was the time when you knew that even if a player had a MP against Federer, he wasn't gonna take it, doesn't matter what.
You got it right on the entertainment factor - those were pretty nice matches, for the most part.
Well, you seem to agree about the Paris match. And I remember the Miami final well because it was so closely-contested and Ljubo had so many chances. He had at least one SP on his serve in one of the TBs and as a case of a series of mini chokes against the mighty Fed it was really similar to the Davy v. Fed encounter in Paris '07.
Even in the Miami presentation ceremony, Fed conceded that Ljubo could have made it closer if he'd taken his chances. Fed did NOT play clutch on all those SPs, but neither did Ljuo. When it was all over I could hardly believe it was a straight-sets result.
Ljubo only had one set point, in the third, which Fed saved well. But he did lead the 2nd set TB 4-1 only to not win another point. He also led the 3rd set with a break but played worst service game of match to return to 3-3. And he also won four more points overall in the match than Fed. No great choke, but nowhere near clutch enough.
