no question winkleman is the better player overall. but depending on the situation you might make a case for bringing him off the bench. it doesn't look like you needed him to score much last season. but if you need a bench scorer, he'd probably fit the role.
like you said, Rose is more vulnerable to press given low BH, speed... and I'd hesitate to use him against a fast SF who was a big scorer for the other team due to his 40 spd. with such high ath it would be interesting to see if Rose could score off the bench too, making a good case for winkleman starting almost exclusively. the rebounding rating is pretty low for both, so I'm not sure that will be much of a factor. winkle had some rebounds last season anyway... too small sample size to see about Rose in that area.
