And that all means what?
Whoever they take with the 1st overall pick will have a cap hit of 950k. That's the maximum allowable ELC salary for a player drafted in 2022 as defined in the MOU. He'll get max bonuses of 2.85 mil, but teams are allowed to exceed the cap via performance bonuses by 7.5%. 7.5% of 82.5 mil is 6.1875 mil.
3 other players on Montreal have performance bonuses in 2022-23:
Caufield: 850k
Jordan Harris: $507,500
Justin Barron: $212,500
Added to the 2.85 mil for their 1st overall, that's a total of 4.42 mil. That's well below the bonus cushion, so they won't have to account for any of it under the 82.5 mil cap. None of their other prospects have significant performance bonuses, so even if other prospects make the team, it won't be enough to go over the bonus cushion.
So they can fit Wright, or whoever, very easily under the cap.
Montreal is going to be actively trying to move other players, players who actually have value. They aren't going to give up a 1st round pick to get rid of Drouin. If Drouin actually had the value to be our 2C this year, Montreal wouldn't need to give up a 1st round pick to move him, so your entire premise is flawed.
