Who roots for the Pacers here?
If nobody wants to pick for them from that fan base, I'll leave that up for grabs.
I think that's the only team in question.
What I mean is that eventually teams give their lottery picks that chance to fail in the starting lineup. so if you do draft Dunn he'll come off the bench, and whether or not he's ready within a year or two you'll start hearing that he should start regardless of his performance - Either he'll be too good to stay on the bench, or people will say he needs to start so you know what you have (Teague & Schroder situation)
I'm not worried about 2 years from now. It's a great problem to have if in 2 years that pick is good enough to unseat anyone in that lineup (that becomes a massive trade chip worst case scenario). Not just Dunn, if Murray can do it, if Hield can unseat LaVine, if Poeltl forces Towns to PF, if Jaylen Brown forces Wiggins to go, create a situation.
If they have a Teague /Schroder situation, good. If they're in the playoffs by then, even better. Also, in 2 years, Ricky has 1 year left on his deal. They'll have a better clue of what to do with him as well as the rest of the team.
At the very least, Dunn could help alleviate the problem of the backup PG on this team being much worse than Ricky.
