Why?
He was awful this year as a host.
So cheesy and awkward and inappropriate .
He wasn't even funny.
His jokes didnt land

Acting weird towards cardi on stage after she performed WAP.

He is a good late night host, but he was out of his element hosting an award show like the Grammys.

The Grammys should have a master of ceremony, a fellow musician like LL cool j or alicia keys. Somebody that will pilot the show, not someone who will crack awful unfunny jokes.
