When the Kings traded both Buddy Hield and Tyrese Haliburton for Domantas Sabonis back in February, the shooting guard position became a bit of a question mark for Sacramento after previously having been a position of strength. After the trade, the Kings primarily used the newly acquired veteran Justin Holiday, with Donte DiVincenzo playing most of the backup minutes.
Neither Holiday or DiVincenzo are on the team anymore but the Kings did bring a few guys in who could reasonably fill that hole.
The Case for Kevin Huerter
Perhaps the biggest acquisition of the summer for Sacramento (aside from Keegan Murray) was Kevin Huerter, the 6'7 swingman from Atlanta. Huerter spent his first four seasons in Atlanta and started most games for them at Shooting Guard. Huerter gives the Kings the most size at the position, as well as being the most consistent shooter. Huerter is also locked up for four more years, and given that the Kings invested a future first round pick into acquiring him, it makes sense that he's probably the favorite to start. However, I do think there's a possibility that the Kings will play a little bit smaller and as a result play Huerter at Small Forward instead, moving Harrison Barnes up to Power Forward and leaving the Shooting Guard position open to someone else.
The Case for Malik Monk
Monk was another big acquisition for the Kings, coming off a career-year with the Lakers, where he started half the season. As a starter, he averaged 17 points on 47.8% from the field and 42.2% from three to go along with 4 rebounds and 3.3 assists. Monk also has previous experience playing with Fox back in Kentucky and is probably the most athletic of any of the options. However he's also probably the weakest choice from a defensive perspective. While I could see him starting in a small ball situation like I described above, I do think that with coach Mike Brown's defensive mindset that Monk will instead operate off the bench as a 6th man scoring punch.
The Case for Davion Mitchell
Davion Mitchell is an unlikely choice because he's the team's primary backup Point Guard, but he's also probably the best individual defensive player on the team. Mitchell's not terribly big for the Shooting Guard position but he is plenty big and skilled enough to guard the opponent's best backcourt player. Offensively though, he's probably one of the worst fits. He's the weakest outside shooter, and as we saw in his rookie season, he's best when he has the ball in his hands. Sharing the ball with De'Aaron Fox would probably mean he'd have to play more off the ball and out of his comfort zone.
The Case for someone else
Now I don't see the Kings considering anyone else, but I've also seen weirder things these last 16 years. Could Mike Brown want a veteran like Kent Bazemore or Matthew Dellavedova to start as tone-setters but then play limited minutes for the entire game (kind of like how the Kings used Mo Harkless in his time here). Or could we see another trade before the season begins that brings another option in? Again, I think that's pretty unlikely at this point.
If I had to bet on who is named the starter from Day 1, it'd be Kevin Huerter. He's got the experience and he provides enough on both sides of the floor, whereas the other options are a bit more awkward in terms of fit. All three of those players will likely see plenty of playing time, but Huerter makes the most sense to me as a starter.
