Deni will be our backup point guard
		
		
	 
which would mean that Portland desperately needs a backup PG because Deni is 3 zip codes away from being a PG
so far, this season, he's averaging 4.2 assists, but 3.8 turnovers. That's an assist/turnover rate of 1.1; a rate that would get any PG fired
in fact, there's this record for Deni:
rookie season: usage rate 12%....assist/turnover 1.91 (
assist rate 6.3%)
2nd season: usage rate 16.3%....assist/turnover 1.92 (
assist rate 11.8%)
3rd season: usage rate 16.7%....assist/turnover 1.71 (
assist rate 13.9%)
4th season: usage rate 20.2%....assist/turnover 1.79 (
assist rate 17.8%)
5th season: usage rate 23.2%....assist/turnover 1.43 (
assist rate 19.9%)
this season: usage rate 26.6%....assist/turnover 1.1 (
assist rate 20.1%)
note: all the usual escape clauses about different teams, situations, and sample sizes. 
Also, it's more difficult to find breakdowns of ball-handling vs passing turnovers; maybe I just haven't looked lately
you would expect turnovers to increase as a player handles the ball more. But for a PG, as the experience & usage increases, along with the assist rate, you'd expect the assist/turnover rate to at least keep pace and not get worse. Deni's best season in terms of usage, assist rate, and assist/turnover rate was his last season in Washington. But that season, he was actually 4th among starters in assists/game and assist rate. He played with a PG and couple of same-level secondary facilitators. His burden was a lot less than it has been in Portland. 
what I have seen is that Deni is a willing passer. But his passing skills and court vision need a lot of work. As I mentioned, some of his turnovers are part of his turbo mode and those are not necessarily passing mistakes. Those breakneck dribble-drives generate some turnovers. If Deni is going to be the secondary facilitator/PG, he's going to need to scale back his turbo mode, but that might make him less impactful
