Based on how he looked in the pre-season and his limited time in the regular season, I doubt he looks like crap in practice, especially against this awful defense. It likely has more to do with Pettine wanting to keep his job. He probably views being competitive as easier to sell.....hey "we're close!".
My preference in playing Manziel had nothing to do with how I thought McCown might play.....it had more to do with finding a potential resolution at that position. I don't see why you invest a 1st round pick in a guy and then opt to keep him on the bench in favor of an average journeyman QB. For a good NFL QB that can get you somewhere? Sure.....for McCown?....you just can't sell me on that. I have no idea if Manziel will even develop in to an average QB but I'd rather find that out than watch a guy who's going to get us nowhere guide us to a 4-12 record.
Browns now sit at 1-3 and have played just one team on the plus side of .500 (New York), who absolutely blasted them. Schedule only gets tougher from here on out. Team is going nowhere and yet we're going to keep carting out a guy who does nothing for us long term and only a little more in the short. I'm sure this is where all the people break out the "loser mentality" quotes. Have at it.
