I am almost at the end of this process, looking at about enough film of prospects and watching current state Raptors to see what player would fit. My pick is the guy I knew would make sense at the beginning of process: Devon Dotson
Toronto is essentially built on defensive activity feeding transition scoring -- which is exactly what this player does well.
His speed is really translatable to the NBA considering how well he can finish at the rim with either hand and create even without screen usage. Ranked 1st in his conference in transition scoring (4.9 ppg); At the rim scoring is almost like a big at 64.1%.
His defense is aided by his speed which allows him to jump into passing lanes (3.6 steal%) but he can defend on-ball 0.44 points per isolation possession [88th percentile].
Despite being a scorer he knows how to run a team and is a 5 star recruit and an All-American.
Basically the guy is the controlled chaos Toronto needs off the bench.
