I've got absolutely zero evidence to back this up, but I just have a feeling that Paul isn't COMPLETELY done yet. They probably won't contend this year, but I doubt it'll be as horrible as 2013, either. Let him have his farewell tour, he deserves better than whatever the hell 2013 was.
For the record, that's just me being sentimental. I'd welcome him back for another year, but it won't be the end of the world if it's time to move on.
