2. Danny Green - SG/SF, Philadelphia 76ers
This one should make many fans of the mid-2010s Spurs happy. As the first team to give Danny Green a real shot, the Spurs enjoyed eight seasons of Green's 3-and-D game that was close to being the most unexpected NBA Finals MVP of all time in 2013.
Three-plus seasons removed and with two more NBA titles to his name, Green still showcases the same skills for the Philadelphia 76ers at age 34. Danny was deadly from the 3-point line last season, nailing 40.5% of his outside shots on a career-high 6.3 attempts per game. This season, he's at 39% on 4.8 attempts.
Green would have no problem being re-integrated into the system that molded him into the NBA player he is today, but his role on the 2021 squad would be more of a veteran presence that can get hot off the bench.
I don't see Green being the focal point of a trade with San Antonio, but he could be a filler thrown into a multi-team trade, particularly one involving disgruntled Sixers star Ben Simmons.
