Just don't get it. There goes a chunk of minutes from Bogdan, Malachi, Temple, Jackson or whoever else. I really don't want to watch a bunch of old washed up guys take away valuable playing time from the younger players. People are taking this whole mentor thing way too far. It's not necessary to have a mentor taking up 25min a night at each and every position. We already have enough on the team. I don't want to watch that crap all year.
Well, Temple is 31 so I don't see why Carter potentially taking some of his minutes is a big deal, but I see what you're getting at.
But if Jackson, Richardson and Bogdanovic can't beat out 40 year old Vince Carter for minutes then it gives them something to shoot for. Motivation to work hard in practice. To work hard in the weight room. To put up extra shots before games. To get better each day.
Having mentors for young guys is huge. It's guys showing them how to navigate the NBA life, how to avoid pitfalls they fell into, how to break down film, how to communicate on defense, how to bring effort every game, the type of work ethic necessary to keep you in the league for a long career, proper nutrition - in short, how to be a pro.
And on the court it forces them to grow.
When young guys are just given PT right off the bat there's no mechanism to correct bad habits and force them to play the right way other than the coaching staff getting on them and that only goes so far. But having a veteran in front of them, or coming off the bench behind them forces them to adapt. To play the right way if they want to earn minutes. And it makes them hungry for those minutes.
We saw it last year with Malachi. Coming up from Reno and actually getting to play NBA minutes, you could see it meant something to him. He worked hard for the opportunity. And while I'm sure he would have liked to have gotten 25 mpg and played all year, if you asked him I bet he'd say it made him a better player and made him want to work harder moving forward.
