61) Devin Booker
Phoenix Suns star Devin Booker was still coming into his own during the 2010s while still on his rookie contract. Booker was one of the younger players in the 2015 draft class and even though he was selected 13th overall, he quickly emerged as a star. In his second season, he saw his scoring jump by 8.3 points per game, with Booker famously dropping 70 points in a game in 2017 at the age of 20.
That was just the second time in the 21st century that a player dropped 70, with him being only the second since Kobe Bryant. He closed out the decade by putting up 24.9 and 26.6 points, respectively, and in four seasons, he averaged an impressive 21.4 points per game, although he failed to make an all-star or All-NBA team during that stretch.
That may have had a lot to do with the Suns being largely terrible during the 2010s. Actually, they missed the playoffs 10 straight times from 2010–11 to 2019–20 before going to the NBA Finals in 2021. The 2020s were definitely better for Booker but he still showed that he was a rising star in the 2010s.
