Honestly, I dont think there's much to work on with him besides stats . There's really just a lot of lions up for stud and everyone has super different taste so unless you're selling to a really niche market with fewer studs, on the LB, or have the newest trends a lot of males don't get stud requests as often .

Personally, I would remove slot 7 or 8 . 7 because many don't like the markings or get tiresome of seeing them on so many studs and additionally if the marking that fills the space doesnt go well, theres still 3 slots above it to help things until you change it . If you like that marking and want to keep it, slot 8 would be my choice because he already has an undermarking in slot 10 .
