Drop ShagNasty for Ahtyba?

Anythoughts on this?  Dropping Shagnasty for Ahtyba?  Last year in my leagues scoring Ahtyba (man i hate spelling this) was 4th leading scorer althought Shag didnt start all of the games last year.  Trying to put it in retrospect!  Thanks

I would hold off and wait until we get more info on Shag Nasty's injury. Rubin is a nice pickup but doesn't have the upside of Shaughnessy.
