Until this summer, I thought I knew exactly how cap holds work. The couple of sites I use show Utah has cap holds in place for Hill, Withey, Mack and the two 1st round picks, but not for Hayward. Spotrac has now updated their cap/cap hold numbers to show Ingles at $11.6M. I think the Ingles signing now counts against the cap, although the contract isn't officially in force until July 6th.
Spotrac site, which I've found updates the fastest, now shows Utah with $98.8m in salary and $25.3m in holds. Salary included Diaw at $7.5M. And the holds which likely come off the books at some point (Withey, Mack, Hill) total $21.3M.
