Yeah, sporadic success, meaning inconsistent performance for whatever reason, though Detroit has been fairly consistent.
Even Manziel couldn't make Cleveland good.
Living in Cincy I would in the past pay a bit of attention to their team and they seemed always to draft some high draft pick QB who flopped. It was predictable. Ryan Leaf I think one was. I started to think perhaps the "issue" was not with the QB. And yes, they have a major front office problem too.
