Injuries often help those oddball picks make the game.
On the plus side, LaMelo and Middleton have been injured opening up a couple of spots. (Middleton is more position-fluid, similar to DeRozan and Jaylen).
But it doesn't help that 2 All-Stars came over from the West without any going back out (Mitchell, Murray), plus Jalen Brunson came over too, another contender for a guard spot.
Haliburton, Maxey, and Cunningham are all on the come up with nice stats (and varying degrees of team success).
Vets Beal and Irving were absent from the team last year and I'm sure want to make the team again this year.
Trae Young ain't giving up his spot. Neither is DeRozan (they classified him as a guard last year).
Garland, Lavine, and VanVleet all have numbers (and one of them is already going to have to make room for Brown, who will probably be considered a guard), personally I don't expect Lavine or VanVleet to be back.
Harden's a wildcard due to injuries (has missed a month so far)
And if you're looking for a scrappy guard on a great team, then you also have to consider Holiday (better stats and helping keep the Bucks near the top of the standings with Middleton out, though Brook Lopez is making a case as the 2nd Buck too).
All that to say, a lot of competition at the guard spots. Would be cool to see Smart make up, but I wouldn't get my hopes up.
