According to ShamSports, Johnson’s contract (just over $1 million) combined with the non-guaranteed deals of Moore ($762,195) and Williams ($915,852) will free up roughly $2.75 million in cap space for the first year of Lee’s deal. The details of Lee’s contract have not been made public yet, but John Hollinger of ESPN has an estimate of what the deal may look like:

Lee's deal would pay a max of $4.25M in first year and $18.15M overall if its for four years.
