Why is that?

Alex Smith was sacked 6 times and they nearly blew a 20-7 lead. Had the Browns punt returner not fumbled a punt at mid-field late in the game, Cleveland might have won.

Granted, the Browns are a tenacious team, but I don't want the Chiefs believing they can play that badly in the 2nd half and still come away with a win. I'd rather they lose a game and learn from it. This is the kind of win that troubles a head coach.
