I think that is correct.
I believe both Eric Fisher and Mitchell Schwartz can be released by the Chiefs even though they are injured.
For Eric Fisher the guaranteed portion of his contract of $19,487,977 has been paid to him. Eric has a prorated bonus which will still count against the 2021 cap for $3,181,668. This would be considered Dead money. The Chiefs would save Eric's base of $11,250,000 plus his 2021 bonus money. -

Mitchell Schwartz had $6,250,000 of guaranteed money which has already been paid. He also has a prorated bonus that would end up as $3,750,000 of dead money but would save Chiefs $6,098,750 of cap space by releasing him.

The issue that people get confused by is guaranteed money. Alex Smith had a huge contract of guaranteed money with $44,000,000 which made it very costly to release even when he was injured.
