I'd say 6-7-6-7 is still marginally good, as compared to those 4-5-6-5. For me it depends on his quality. I had a scout at 4-6 ratings, but I'm not selling him just yet to see if he can perform next season. If it were a 4* player and not performing well with bad rating, I'd sell him cos by next season he would have been a 3*.
