This is the wild card. There is no definitive answer that Johnson is permanently on LTIR. As of 4 weeks ago, Johnson was still hoping to be able to play again and Colorado might be forced into buying him out if he gets medically cleared. If they have to buy him out, that's 2 million against the cap for 4 years.
Erik Johnson “wants to play” but symptoms persist
If this so (UFA + possible trades):
E. Johnson - $4,000,000
Girard - $5,000,000
Graves - $3,166,667
Nemeth - $1,500,000
Saad (maybe) - $5,000,000
Nichushkin/Compher - $2,500,000/$3,500,000
----------------------------
$21,166,667/$22,166,667
Jones - $5,400,000
Makar - around $8,000,000 (+$7,119,167)
Landeskog - around $7,571,429 (+2,000,000)
Grubauer (or better goalie) - minimum $5,333,333 (+$2,000,000)
----------------------
$16,519,167 round to
$16,300,000
but
Burakovsky ($4,900,000) contract to 2021/22 UFA
Kadri ($4,500,000) contract to 2021/22 UFA
and it`s only math because if Avs don`t resign, for example, Saad they must find another player/s.
