Is he one of the greats? Hell no. Is Brett Lee one of the best bowlers in the cricketing world today? Definately, but I'm not sure if that's much of an achievement. However, it's unclear as to whether Mark Nicholas has referred to Brett Lee as an all-time great, or as one of the great's of today's game, or as one of the all-time great ODI bowlers. Mark's comment is really very vague, so I'm not going to read too much into what he said.
