Because they have a vested interest in the team's profit. That's going to taint their opinion especially on something as philosophically diverse as rebuilding vs retooling.
That was the first red flag in their post. The 2nd was the "im a fan and always want a win". I've had this convo countless times across different sports and it's tiring, so before digressing I'll leave you with a question -- what's the difference between:
1) Being a fan of a team and always, always wanting them to win the game. Can't fathom wanting a loss.
2) Being a fan of a team, but also a fan of talent which is entertaining and aesthetically pleasing. But what's the holy grail? Having upper-echelon talent on your team. It's infinitely more enjoyable this way.
Put it this way. Gun to your head, deep down, in your heart of hearts... is there a chance your team can win it all? Can it be considered among the top-10 teams in the league? Is there hope? Upside? Ceiling?
Yes? Then getting so invested in your team that your rabidly cheering on every single puck battle on the edge of your seat is worth it.
No? Then what's the point? You're team's a loser. Be a fan of talent first and enjoy the league. Why waste time watching crappy players knowing they don't have a chance? There's no reason to get invested in the team if they don't have at least 1-2 cornerstones/pillars. You can still be a fan and keep your eye on them, catch a game every now and then, but... c'mon, really?
I digress.
