I'm not saying it will happen, but I would put it at a small enough percentage that I wouldn't faint when I heard the news.
Besides . . . .
This summer, they're already at the full cap without Manu or the MLE (Splitter). That's filling the roster with TD, TP, RJ, Dice, Hill, Blair, and picking up Hairston's minimum.
7 players, 5 more active roster spots to fill +1 inactive, and doing anything like re-signing Manu or the MLE gets them closer to the tax. , they could be over the tax just by re-signing Manu if the cap drops enough.
