So reach for a 3-4 to fit need instead of taking BPA?
Late in the first round a lot of BPA becomes in the eye of the beholder. It is to tough to say who is better then the others. Besides you always look to upgrade at the depth in the late first.
Rubio is solid and even potentially great but is he the future? Exum is solid and has a ton of potential but he is a RFA and if a team offered him a killer contract the Jazz would probably let him go. Neto is OK and a FA but could always look to improve there to (Jevon Carter)
Mitchell is the future and 1 of 2 players that can't be replaced. I expect Burks to be moved. O'Neale is solid but you can always look to upgrade
Ingles should be a Jazz man his whole career and hopefully after, but he is replaceable in the starting line up as he ages. Crowder is solid but streaky and could be looked to be replaced in the future but his flexibility to play multiple
positions helps the Jazz. Sefelosha (IMO) needs to be replaces because coming back from a major knee injury at his age is hard and not worth the gamble as he is replaceable in either the draft or free agency.
Favors is a free agent and there are still questions marks about his long term fit on this team and against smaller line ups. Jerebko is a solid bench player but is he better then a 3rd option at PF.
Gobert is the other player that irreplaceable. Udoh is a decent back up but limited offensively. Bradley seems to be being groomed to be the back up but again you can't pass on improving here.
So the only spots that would be hard to replace are starting PG, SG and C. Every thing else can be replace or improved upon.
