There was a time when Jason Kidd was considered the worst shooter ever!!!!
Statistically he was. In fact, whenever a shooter has a sub 40/30/80 season, they term it a Jason Kidd.
Now Kidd is one of the better spot-up 3 point shooters in the league.
Although I hope Rivers develops quicker than Kidd...he is already much smarter.
Everything you said was true, but Kidd was also a dynamic player despite being a poor 3 pointer shooter. He was co-ROY and a top 5 player in the league 6-7 years in. He became as spot up shooter late in his career. Otherwise, he developed just fine.
