CLEVELAND — Welcome to what should be the beginning of the end of the Deshaun Watson era in Cleveland. It won’t be, because Browns ownership still doesn’t get it. But it should be because Sunday the Browns played harder, with more purpose, intensity and, especially at the end of the game, with more heart than at any time during the sputtering, sporadic, lurching, on-again-off-again, unfocused, discombobulated, please-make-it-be-over Watson era.
