Bill Russell is 2.reasonable what ifs and not breaking his ankle in the finals from having won every championship he possibly could have from age 16 to 35.
Even without what ifs he won back-to-back state titles, back to back NCAA titles with 55 wins in a row, and 11 of 13 championships in the NBA with an Olympic gold medal by the widest margin of victory ever outside of the first dream team. Two the Championships he won... he coached the team to. The players not the media voted him the MVP five times. He literally played all five positions. At one point he was like 4th in the NBA in assists and first or second in rebounds while scoring as well and blocking shots at an unheard of rate.
His whole career and to this day people at like he won because his team was ridiculous and his college team had never made a tournament before him and only made 1-2 deep runs in the 60 years since he left and the Celtics missed the playoffs back to back seasons when he retired and lost in the finals when he broke his ankle mid series. And that team had three all NBA First Teamers before he got there and never even made the finals. People said it was Red...then he coached them to two titles himself. Red never even made the finals in 16 years of coaching pre Russell despite having the best record in the league several times.
Bill Russell practically created victory. I bet he would have found a way to win the gold in the high jump had they let him compete in both that and basketball at the Olympics. He was ranked number 2 in America and was high jumping six nine and change going over the bar forward doing track in his spare time.
If we are going to give him the what if treatment his career only takes a couple to be completely unblemished from middle school to retirement.
ussell won everything he competed for. Everything.
Not like he was the only one playing. I cant call it an era thing while other all time greats were losing. Elgin Baylor lost 3 game 7s to Russell by a total of like 7 points. Thats not Elgin being in a different era. Its Russell not letting his team lose. He had a 30/40 game 7....a 25/30 something game 7 where he outscored Baylor....who he covered much of the first half and held to 1-9 shooting.
Guys just kept coming up short vs Russell.
Hes dropping 25/28/14 triple doubles. He was the worst Ft shooter in the NBA and he shot 70+% in game 7s. One game they tried what we now call Hack a Shaq....game 7 for the title...he goes 14/17 from the line. A 55% shooter....he sinks 14/17 to win the title by 2 points. 3 years later he was perfect from the line in game 7...another 2 point win for the title.
He had finals winning blocks. Finals game winning baskets. A finals game winning putback dunk. Set a still standing finals record for shooting percentage(70%) in a season he only shot 43%. To closeout the 63 finals...he had only 12 points...but 24 rebounds 9 assists...and he blocked 8 shots 5 of them Jerry West jumpers in a 3 point win.
Bill Russell refused to lose.
Plenty of others were in the same league. But he would do whatever it took not to lose.
