There are other factors with PT. Yes, getting minutes does get a player comfortable with being on the court and game speed. And, it takes away some of the 'deer in the headlights' effect that hits a lot of kids.
Minutes also do is they motivate kids (rather than just the negative motivation of sitting the bench until you play better in practice). The kid gets a positive taste of the game and being part of the team - however small it is. If you get 2-3 minutes in the 1st half, you get to participate. Even if you are
But, there is also another benefit. Many of these kids, whether it's completely spurious or not, doesn't matter, think that if they are not getting minutes in games their game is being held back and they are not given a chance to develop. But, give a kid minutes in several games and if his game needs a lot of work, he'll be exposed. And, most importantly, he'll be exposed to himself. He'll see he is getting embarrassed on national TV if he doesn't up his game.
I think there are three key motivating factors for everyone - but especially for freshmen coming in. And, all these have to actually be experienced. The "stick" the negative of seeing that you are not going to start or get a ton of minutes if you don't work hard. The "carrot" - a taste of success. They have to feel the taste of being cheered by fans at home. Getting a big play in a game (even Bolden has had a play or two). The more opportunity they get for that the more motivation there will be in practice. Making a play in practice and getting the praise of an assistant coach is not motivation enough. Third, is relational. A kid needs to know that the coach really loves him and wants him to have a great experience as well as grow. That means some PT.
This is not saying a kid like Bolden should have gotten 10-15 minutes a game. But, that he should have gotten in many more games, most or all of them, at least a minute or two. And, if Duke has a lead maybe give him 5-7 minutes and I think that would go a long way to their desire to stay; to work harder the next year; and to believe that they actually will get on the court. That they won't turn into a Sean Obi, sitting on the bench for 3 years (whether that's fair or not, doesn't matter, it's perception - and that's why so many transfer out of Duke after their freshman year).
We'll just agree to disagree.
