He doesn't, really. It's made for chicken shit heels or mid carders they only give the belt with the intention of getting it off somebody in a screwy manner. He's too over to keep pushing him as a chicken shit heel.
Honestly, MITB works great for Logan Paul (Shows up randomly) and his character. Make a screwy finish where Knight was gonna have it and lost. Have Knight continue about how he's handed nothing and keeps getting held down.
Then give us Knight vs. Paul in the fall/winter with Knight going over. Gives Knight some mainstream attention and Paul can eat the loss because he's still got the briefcase.
