Ask yourself this... When PG or Jimmy Butler get to the rim, is it because they "beat" people (i.e. accelerate past them) or is it because they are in control and use their body to shield their layups where they're able to finish with craftiness around the rim? Usually, it's the latter. They just need to get a player on their hip and be going towards the rim, and they likely score.
Hutchison does this well. He's shown a level of control, craftiness, and ability to use his body to put himself in a position to use those skills that translates to the NBA well. It's very rare that SFs end up being players that consistently blow by their defenders in the NBA, so beating guys off the dribble in college isn't what I look for. He's able to accelerate just enough to get next to a defender, and he knows how to score from there.
When you look at Khris Middleton, Kawhi Leonard, and Jimmy Butler at their time in college, none of these guys shot off the move or had efficient mid-to-long-range jumpers. Kawhi was pretty much a ser shooter. So how did these guys turn into players that could do that? Elite work ethic, which Hutchison has.
To worry about mid-range and off the move shooting is silly with Hutchison. He barely tried to do so in college, so who knows how effective he is. He can be a great player without those things, but I have no doubt he can learn them. He was never a confident jump shooter until his junior season, so with ever-growing confidence I believe his shot-arsenal will continue to open up.
The dude has an extra gear, work ethic, as well as some skills on the court that Bridges doesnt have and that you can't teach easily (elite body control, ability to finish at weird angles, some ability to change pace, quick first step, some passing vision, ability to keep his body and his dribble synchronized, etc.)
I also believe Bridges had the luxury of playing on a great team while Hutchison didnt. Bridges has a better percentage, but he gets a lot more open looks than Hutchison due to playing on a Final Four team. Hutchison was also tasked with trying to distribute for a mediocre supporting cast, and many teams would load up on him defensively, which would be a main reason for his struggles, based on a heavily-loaded defense that he wouldn't see in the NBA so long as he had a decent group of teammates. The 3rd option in a Portland attack would be a great role for him. He would have an easier time trying to create at the NBA level for a team like Portland.
