If you want to compete in blocks 1 pickup is not gonna do it.Two or 3 of those bigs would make you competitive in blocks,but then you'll have to take a hit in other categories.But,personally I'd take Hawes & Hicks over over Gallinari & Marion because they'll make you better in rebounds,points,fg%,AND blocks.
You'll take a big hit @ SF,but category strength is more important than position depth.
are you seriously suggesting to drop gallinari for hawe or hicks?!?! have you lost your mind? no matter what category you need, the value for gallinari is way too high to be dropped for bench players!!
