Really? You can give a player a June 1 designation and get the cap relief instantly? I hadn't heard of that. As far as I know the drawback of the June 1's is you can give them the designation early, but you still have to carry their number until June 1.
That is what Omar said, will take a look around and see if I can find something to support that.
Maybe this is what he is referencing..but it doesn't seem like immediate relief.
One of the more complex phrases prevalently used this time of year is the Post June 1st release. I’ll do my best to explain this in layman’s terms as it most often applies to a player.
Real Example:
The Cowboys recently released WR Miles Austin, designated him a Post June 1st Release. He carries $7,855,600 in total dead cap right now, $2,749,400 of which is allocated to the 2014 cap, $5,106,200 if which will accelerate to the Cowboys’ 2015 cap.
The first thing to note is that Austin is being released on March 12th, and being designated a June 1st release. Per the rules of the CBA each team has the option to designate two players per year in this manner. The catch here is that Austin’s current contract must stay completely active on the Cowboys’ books until June 2nd. This means his original $8,249,400 cap figure will remain on the Cowboys salary cap until this time.
One June 2nd, all Post June 1st Designations are properly allocated in this manner:
Any bonus money allocated to the current year (2014) + any guaranteed salary throughout the remainder of the contract turns into 2014 dead money. In the case of Austin this includes the $2,749,400 in restructure bonuses.Any bonus money allocated to the remaining years of the deal (2015+) are accelerated into 2015 dead money. In the case of Austin this means $5,106,200.

Or maybe this:
If a player receives a $5 million signing bonus for a five-year contract, the player gets a $5 million check upon signing, but the money is prorated for salary cap purposes—counting $1 million per year for each year of the contract, including the year it is signed. This is a way of giving players a bigger payment with less of a cap hit, but there is a potential downside called acceleration.
If the above player is released after year-one of his five-year deal (4yrs remaining), the $1 million yearly signing bonus payment—spread out in the contract—now accelerates, or is added altogether, onto the current year’s cap. It becomes dead money or a cap charge for a player no longer with the team.
Under this scenario, if the player was released before June 1, assuming the contract was signed in 2014, the team would lose $4 million in cap space for 2015. But if the player is released after June 1, the team has a dead money cap charge of $1 million in 2015 and $3 million in 2016. The team still has a dead money hit of $4 million, but the acceleration (adding together of the prorated bonus) now takes place in the following season.
So a post-June 1 release gives a team more resources in the current year, which they may need, and pushes portions of the charge to the next year.
