For me, he's like blue cheese. Takes a while to appreciate. I am impressed with Lendl simply because of his work ethic. Some folks say you're simply "born" to do whatever you do, others say you have to develop yourself. Lendl developed himself from a modest player (top 100) to a superlative player. He took advantage of the tools he had. I hated watching him fall apart during the early years. But his hard work paid off. He became competitive. He, with Martina, raised the bar and has helped tennis become a more athletic endeavor. At least that's my simple take on it.
