Saints Draft and the Cap

I am wondering how drafting at the 15th poisition affects the cap for NO. If they traded back to the 20-25 area would they still be able to get a player they want and save a million or two on the cap. I believe the cap is now structured as to where you are drafted so there is not much mystery to the slotting moneywise anymore. Could this affect NO's decision to stay at 15?

Almost no difference.

Last year, the 15th, 20th, and 25th selections were Irvin, Wright, and Hightower. Their first year cap hits were 1.7M, 1.5M, and 1.4M respectively.

So, you're talking 200-300k savings. aka Small Potatoes.
