A little more research shows that Gibbs has had some lopsided games other than the one against Carter, and honestly the 25 point loss wasn't the worst one.
12/8 Gibbs 50 - Fulton 87 (-37)
12/29 Gibbs 83 - Berean 60 (+23)
2/2 Gibbs 59 - GP 83 (-24)
2/4 Gibbs 80 - Carter 105 (-25)
I think they are upset not at the fact they lost by 25 it's that they lost by 25 and gave up 105.
Gibbs is averaging 72 points per game and giving up...73....
