On the Dan Patrick Show Manziel takes a haymaker shot at playing in the spread offense and partly attributing that to his struggles in the NFL. He's very candid about his lack of preparation and work ethic as being the reason he flopped. Unfortunately, in doing so he threw Cleveland under the bus. Which doesn't come across as I know he intended it.
