Remember how Trump had his GOP Convention in Cleveland, and then met at the White House with Obama, the same day as James? That was November 10, 2016, the same day the Baltimore Ravens hosted the Cleveland Browns.
11/10/2016 = 11+10+20+16 = 57
Also, remember how the Cavs won 57-games in the regular season last year? '57', our championship number.... here's another.
