"but Pettine seems to hate him and be looking for any excuse to sit him" I think this too. I think the owners kind of pressured Pettine into naming Manziel the starter the rest of the season, because they drafted him and wanted to see what they have. But Pettine is on the hot seat and had an itchy trigger finger and was just waiting for any excuse to bench Manziel. Srsly, he didn't just bench him either, third string.
