I just read on gopokes that this whole thing is not a problem.
Apparently, Cezar is the best PG and he was having his minutes stolen by Fred and Reger, so now that they are gone (still unclear on how Ford ran them off by giving them more playing time) Cezar is going to shine, much like Weeden did. Also, Reger and Fred left because they didn't want to compete with Cezar. This is the part that seems to defy logic, but they seem very confident about it. Apparently, by them getting more and more playing time, Reger and Fred could tell that Cezar was going to take the lead spot at point. :facepalm
