Josh McCown done for the season-Now What?

The Cleveland Browns announced that Josh McCown suffered a broken collarbone in their loss to Baltimore Monday night and will miss the remainder of the regular season.
McCown completes a competent regular season with 12 touchdown passes against just four interceptions,but the Browns would win just one game that McCown started (over the Ravens) during the season.

Now that McCown has exited stage left (even),the Browns have some decisions to make.
The first of which is bringing back former Buckeye and was released as the teams final cut before the season Terrelle Pryor.
Pryor will be the third quarterback as he is familiar with the system of John DeFlippo from his days in Oakland and training camp and may get some receiver reps as well.

The bigger of the questions is this-which quarterback will be the starter on Sunday against the Bengals-Johnny Manziel or Austin Davis?

Editor's Note-Davis was announced as the starter after this article was written.

Manziel makes sense as the "what can Johnny do" questions are still as valid as from the first pass that he threw,but Mike Pettine would have to let his personal bias go in order to do that.
Davis makes sense as the Browns signed him to a contract over the next few years and the Browns could argue (in-house of course) that it's Davis that needs to play to show his abilities-not Manziel.

I think the Browns should be considering quarterback anyway in the draft,but if I had to make this difficult decision,I'd go Manziel very reluctantly.
Simply because we have one thing on Austin Davis that we don't on Johnny Manziel-a sustained run of playing time of Davis taking snaps with the Rams.
Davis played with ten games with the Rams,starting eight,going 3-5 with 12 touchdowns against nine interceptions,while Manziel would have to start these final five games to match that level of playing time.

I don't think that there is a wrong way to go as legitimate reasons can be given to start either and I'd wouldn't have any problem with either player getting the start.
I think the Browns are going to go 1-4 at best down the stretch and I don't think either player is going to have a better chance than the other to better that possible record.
What it has become is a typical Browns season-Looking towards next season and that season's reason to hope....
