The Packers will save some cap space due to trading Clinton-Dix and Montgomery. The team should save $3.15 million on Clinton-Dix and $379,323 for Montgomery for a total of $3.53 million. The Packers will certainly fill the two roster spots created by the trades. That will reduce the benefit to the cap most likely. If they promote two players from the practice squad who earn the rookie minimum, that would count as $508,235 against the cap. A decent estimate would be $500,000. The Packers could recall Trevor Davis and Jake Kumerow from IR to fill those roster spots. Since they both already count against the cap, the team would realize the full $3.
