By an odd coincidence, the successful basketball team there is called the Devils, and so is the usually unsuccessful football team at Coolsville high school (Cheers For Fears).
In this story, Shaggy Rogers asks Velma about the basketball team name and seems to find it unusual. He may be kidding around, because he's a fan of the football team at his school.
Velma had detention once (and only once) at her school for getting into a fight with a boy named Mickey Murphy after an "overheated debate" between the math club and the science club.
"Friday Night Frights" by Robbie Busch keeps the Gang in good cheer with superb-character based jokes, and an attention to the Gang's camaraderie. The mystery's solution is a no-brainer, and it's still fun to watch Mystery Inc. piece together the puzzle pieces.
Scott Neely makes the most of a good monster design, and he buddies Busch's gags with fitting poses some of which he must imagine without the benefit of a model. For instance, the bit where the Gang split up benefits from Daphne's big grin. Not seen on the show but extrapolated for the comic book beautifully.
