To avoid long run of sevens, bench him for a game... But yet, if MC has long run of sevens, don't bench him lol... Anyway, I don't care how many stars players have if they are consistent performers... Having a striker who gets good ratings, but not scoring ain't bad thing unless you are losing games... Some of them will get good ratings 'cause they are creating lot of chances to other players who don't score (you don't see all chances in commentaries)
