What?
Anyway;
1) According to KOC, they had an eye on Matthews the whole way through and had deduced that he'd go undrafted while they had information that someone would draft Suton if the Jazz didn't.
2) According to KOC, they had a good relationship with Matthews' agent and thought they had him bagged without burning a pick.
3) There are a million things that could've gone differently to where Matthews is either not playing for the Jazz or playing in the NBA at all.
4) There's no assurance the Jazz would have any kind of sweetheart relationship with a player or agent the way they had one with Matthews.
5) There's even less likelihood the Jazz would have any kind of relationship to get a coveted Euro UFA as opposed to gaining the player's rights in the 2nd round (and that's assuming a team doesn't scoop them up after #55, which is likely)
6) Suton sucked, sucks, and didn't deserve to be drafted. Refer back to point 3.
The bottom line is that both the Jazz and Matthews lucked out. If a team can find a way to root out factors that might make a player less available (competition) or unavailable completely (being drafted by another team) by drafting, then draft. The likelihood that the Jazz stumble upon undrafted FA gold 2-seasons in a row is insanely unlikely.
I'll say again, if Bjelica or Randle is on the board at #55 and the Jazz sell the pick, I'll be pissed (but will understand).
