Like a lot of tall people not completely comfortable with their size, Donnell Harvey?s body has taught itself to shrink.
     Harvey, just 21, curls down into a chair, drops his neck so his chin grazes his chest, and speaks so quietly one doubts if he can even hear him.

But tell the Mavs? second-year prot?g? what coaches are saying about him ? oh, and somebody might want to pass the good word to Nellie, too -- and at least two parts of his body stand at attention: His ears.
     ?They did? They said that??? Harvey wonders when told that Mavs assistant coaches are raving about his development. ?They don?t tell me any of that.??
