i don't think she's lazy but obviously she's not going to be a great defender with her height. but she's not quick and mobile as an attacker either, and i think she needs very well-tailored sets, she can't adjust to bad sets. many players can, but not her, so she'll dink. but she's hitting a lot of balls very low, into the block.
tifanny too does that. you'd think they are both tall and would try to hit at the edge of the block instead.
