Cleveland has no delusions of being particularly competitive this season, or getting through the year with Flacco staying up on two legs. Teams carry three able-bodied qb spots on the roster, but only have to have two on the active gameday roster, a third as an emergency qb, sort of a freebie that is listed among the rostered but gameday healthy inactives. That's not going to keep a shithole like Cleveland from keeping 4 on the roster. They know at least one of the veterans is likely to be either on IR or just released at some point during the season, probably sooner than later. They will carry both rookies on the roster, which is why they drafted both, to hope they hit on at least one of them. A preseason isn't going to determine which one is going to end up better or capable of being a starter at some point. It's not a terrible way to mine for a future qb, even though it's Cleveland. They drafted both to try to develop both and see what happens.
