The Mid-Level Exception was used on Lou Williams, which locked in a hard cap of $74.3 million. While the Hawks cannot exceed that number under any circumstances, at $64.6 million in salary, they aren’t close enough to be concerned.
That leaves the team’s Bi-Annual Exception of $1.957 million for Johnson if the Hawks are to pay him more than his offer sheet. Another team could lure him away without restriction with an offer of $1.958 million and the Hawks would have no opportunity to stop it.
Disturbing news indeed, although if any teams are interested in Johnson at just under $2 million, they've certainly kept those plans under wrap.
