all the Darko fans here think he's gonna block 3 or 4 shots a game when only two players (Camby and Kirilenko) blocked more than 3 (but less than 4) per game last season.
He got over 2 blocks per game in 21mpg in essentially the first two months of his career. 3 bpg is not completely unreasonable. His timing and size are out of this world. However I think as he matures and learns defense a little better he will stop going for the block every time (help keep him out of foul trouble) and that'll balance it out a little.
