I haven't forgotten anything, to be honest. The general consensus has been that it will not go up nearly as much as was initially predicted.
The current projections by Street and Smyth and the Sports Business Journal states that the cap will rise approx. 3 million dollars in 2015, and that the "bigger increase" that you are referring to (which they project as 5-6 million) won't occur until 2016.
Beginning in 2014 and continuing through 2015 and beyond, a "recapture" must occur to repay the money that was taken for the slight increase that we've seen in the past 2 yrs--when it was actually supposed to drop a bit, let alone stay the same.
Actually, your thinking seems to be a bit backwards on this. It was Belichick and Kraft who predicted that the cap wouldn't be rising nearly as dramatically as the majority though, and Kraft came out and stated as much. After his initial comments, there seemed to be many who started to agree with him. The owner of the HOU Texans was one who quickly jumped on board with his thoughts.
I agree with you in terms of them being ahead of the curve, but definitely not for the reasons that you are stating. There were ahead of the curve for predicting that it wouldn't go up like everyone thought, not because it was going up.
Of course we may find that it does go up a bit more than predicted which is always possible, as the NFLPA could once again lobby for a borrowing from future years, but even if they did that they'd just be digging themselves a bigger hole.
Here is one very important article to read from the Sports Business Journal, who is a very credible source when compared to the usual mediots:
