If you can only offer a player 2 million a year your demands can't be too high.
I would not even offer him the vet minimum. He can't shoot, and worse still he has not shown the commitment to keep in shape during the season and keep his weight in check. For a pro athlete that is one of the basic things that is expected for you to do your job. He can't even be relied on to show up night in and night out. We don't need guys who can't even make the basic commitment to being a pro. This is not a high demand it is a basic requirement of the job.
While, you may be inclined to throw away $ 2 million on nostalgia, you can bet Ainge won't do so because he is not even remotely sentimental and he has been burned by Jared work ethic in the past, lastly, he is no fool. He could have added him during trade deadline and chose not too. He is looking to improve the team, not make it worse, especially with all the young guys who do not need to be around a guy devoid of work ethic.
