That number is understated.
I believe there is some bad math in there. First, it say "5 players" on IR. How come I only count 4? Are they thinking of Cole Madison as a 5th? Are the Packers paying him? I don't know if Madison is being paid, but I'll exclude him from the following calculation. If he is being paid, we can make an adjustment at the end of this breakdown.
Second, and more importantly, you don't subtract the salaries of guys on IR from what the cap space was previously as the second paragraph seems to suggest (while seemingly contradicted further on in that link). The 3 new IR guys already counted against the top 51 cap and still do as did Ryan (who was out of the top 51 at that point and would have been included in the NFLPA figure above already.) What you subtract from the cap space for these 3 new IR guys is the cap
cost of the replacements.
There is
one and only one definitive source for current cap space status:
https://www.nflpa.com/public-salary-cap-report
Packers: $10,652,977
Catch the notes at the top:
updated daily as contracts are processed. "Processed" refers to the league review and approval of all contracts to assure they conform to CBA guidelines while not putting the team over the cap. There may be some lag between an anouncement of a roster move or contract signing and it being reflected in that number, but not much. Rodgers' and Morrison's revisions to that number should already be in that above figure.
The only subtractions from that number should be:
1) cap cost of the replacements of the IR guys, which would be the rookie minimums totalling $1.44 mil if they are not already included in the NFLPA number; I don't believe they are included because that number hasn't changed in the last couple of day
2) players 52 and 53 also at the rookie minimum totalling $960 million
3) practice squad, 10 players, all 17 weeks, with no above-minimum signings: that $1.29 mil from the link looks about right and I will not bother verifying it
Barring any free agent signings with a cap cost higher than the rookie minimum or vet cuts with a cap savings higher than the rookie minimum, the NFLPA figure should show something close to the current figure minus 1) and 2) =
$8.25 mil
I did not subtract the PS cost because I believe that's pay-as-you-go against the cap from week to week. But if you want to include that as a current liability and eventual cost before the season is out, then that gets you to about
$7 mil in current cap space.
If the Packers are paying Cole Madison like an IR guy, then subtract $480,000 for his replacement.
