A player is worth whatever a team is willing to pay. Bosh
has a max contract but probably isn't a max player,however the Heat don't win a championship without him. Harden makes the Rockets significantly better,his loss from the Thunder won't reflect until it matters for OKC,which is in the playoffs. The term "messiah" is a bit extreme but is Valanciunas struggling? Yes. Can he improve his faults? Yes, it's as simple as that.
