First of all, this is a very good log line. It would probably sell ‘as is’ My only idea would be possibly to take out “honest” because it makes it doesn’t seem necessary and it makes it sound like most high school football star’s are liars (maybe thats just me though). Might try leaving out the specifics on the crime too so people want to read the screenplay to find out. Not that I’m trying to tell you how to write your log line or anything but perhaps something along the lines of…
“A high school football star’s morals are put to the test after his fans cover up his crime.”

Im not trying to say mine is any better, Im just tossing some ideas out there. I’m an amateur writer so take what you want from this review and pitch the rest in the trash haha. Happy Valentine’s Day 🙂
