Three? Gaudreau, Johansson and, who? Whoever the third is, I agree with you, getting rid of the players mentioned previously wouldn't cause the team to completely tank because they still have their most skilled players, and decent depth that they just re-signed.
If we want to tank properly, we need to trade Kaprizov and JEE. They're too old and won't fit the new window, and will keep us winning games right now. In that situation, it's a shame we couldn't also move Spurgeon and Brodin. Boldy is young enough to keep, fortunately.
I think that paragraph makes it clear that a tank is unrealistic. The only way it happens is if Boldy and Kaprizov both get injured for a long time, at this same time as each other. You know, do it the Avalanche way.
