Here's a synopsis of all of their careers thus far.
Donte Greene - 4.5 years in NBA, $5.1M + overseas earnings
Jonny Flynn - 3 years in NBA, $9.5M + overseas earnings
Dion Waiters - 8+ years in NBA, $57.5M
Michael Carter Williams - 8 years in NBA, $22.5M
Fab Melo - 2 years in NBA, $2.5M + overseas earnings
Tyler Lydon - 2 years in NBA, $3.5M + overseas earnings
Malachi Richardson - 3 years in NBA, $4.5M + overseas earnings
Tyler Ennis - 4 years in NBA, $6.5M + overseas earnings
Jerami Grant - 7 years in NBA, $60.9M (plus $20.9M guaranteed for '22-23) = $81.8M
Oshae Brissett - 2 years in NBA, $1.3M (plus $1.8M team option for '22-23) = $3.1M
These 10 guys have made (or are in line to make) a collective $196.5 million overt he last 18 years. That's a lot of money.
I will differ in that I don't think Grant & Brissett are "stars" in the league. Grant's a nice player but never made an all-star team and is putting up numbers on a terrible team. He's a quality player that would be a 3rd-4th option on a playoff/championship contender. Much like he was at SU.
Brissett's in line for a pay day next year if he stays healthy - I'd guess a mid-level exception (around $6-10M) would be the right size bump. If you were to tell me he would be the one from the Brissett-Battle duo that would make it in the league, I wouldn't have been shocked but I would have been surprised. I know Battle had limitations but I thought he had a more than decent shot at a similar level NBA career.
