Per league rules, the Browns can't cut Manziel until next week at the earliest. Rapoport reported the Browns have $20 million in salary-cap space for 2015, which carried over to 2016. Manziel, however, has guarantees in his contract, and the Browns need space to absorb the cap hit in 2015. Currently, they have no space, which is why they will wait for the league year to start.
