Why are people arguing about other players who the Spurs did not select, the reality is about who they have NOW! Luca might not be ready this year and may not play even in year 2---like Lonnie Walker and Keldon Johnson wont play regular minutes until his 3pt shot is better than Forbes, which wont be until the off season at best.
The reality is Luca is not a power forward, he is likely a combo forward, but still has huge upside, Keldon will be interchangeable with Lonnie Walker, but will also huge upside when he hits that 3pt shot.
How Brandon Clarke does or does not do- does NOT matter.
