Not really the same. Ras will make just under 1.5 next season and 1.9 the following season. Ras only had a shortened NHL season played after being demoted to GR for a year following his first NHL season. He had less to negotiate with.
Zadina made the NHL full time at a younger age, and has played more. He has a full 21-22 season, a shortened 20-21 season, and a half season in 19-20 to his resume. His deal will most likely be 2-3 years. He may get less than 2 mil the first year, but not after that considering he has contributed more at the NHL level than Ras had when he signed his deal.
