And idk, I watched the Cavs first round series, Garland didnt look that good (vs a team without great guard talent (and he's got an elite 2-guard who commands the better defender), but who has good guard size). We will see how he looks against a jumbo sized team w/ talent in the 2nd round.
Garland also weighs 190 and has a 6'5 wingspan, so a good measure bigger than Dillingham. Just do yallselves a favor and look at how many NBA players there are in the NBA under 180 lbs. Any success Dillingham has will be an outlier and for him to be highly succesfull in the playoffs would be an even bigger outlier. I think he can definitely become a great 6th man in the NBA and potentially a starter, but for him to be a top 10 PG in the NBA on a playoff team would mean the team is highly optimized around him and he really nailed his potential (becoming a foul merchant, excellent shooter, and passer (aka adopting the Trae Young style game).
