David Lee told him he was not a starting calibur player so yes we can say the club did not value him properly.
That would be a stupid and impolitic thing for Lee to say. David Lee is neither stupid nor impolitic, so I don't believe he said it. I also don't think Haak is lying.
More likely Haak asked for a big raise and Lee said that Haak needs to prove he's a quality 34 game starting player first and then he'll get paid. That's very much not the same thing, but it's understandable a player would hear them as the same, especially when he's not getting what he thinks he deserves. An SD has to be able to say things like that or you can't negotiate.
- Why won't you meet my demands?
- I can't say because you might get insulted.
It's NYCFC's bad luck that Haak more than tripled his minutes played and doubled his per minute goal+ contributions in a walk year.
Haak's per 96 Raw ASA G+ went from 0.10 to 0.20.
Perhaps with making the move for Raul, there was budgetary factors as well, but if Lee had properly assessed a talent that NYCFC has been developing since the academy this doesn't happen.
At the end of the day as an SD you're right or wrong and this is fair. Lee bet that either Haak would not improve so much or Haak would accept the challenge as a positive instead of as a slight and re-sign for a nice raise at the end of the year or that Lee/NYCFC could get someone more reliable at the right price. Maybe the replacement is already done in Raul. Or maybe Lee's decision/error is now Dunivant's problem to fix. That's TBD. You also can't hand out big extensions and raises to every young player who in fact, had not yet shown themselves to be 3000+ minute high impact players.
There's also a universe in which Haak gets a raise and extension before 2025 and doesn't perform as well as he did in our reality because players use perceived slights as motivation all the time and if he's not carrying a shoulder chip he only gets a little better than he was before.
Lee and Haak staked out positions. Haak rose to the occasion and walked. It's his right and no way to stop him short of overpaying him in advance. Not every player goes ham in their walk year, and too many players regress after doing so and signing big contracts. I'd like to have Haak moving forward, but IMO in the universe of NYCFC sporting FO fails this is a blip not a boulder.
