I think Iverson had a decent game. I mean he's playing in a different country with foreigners who barely speak English. That's some culture shock and it will take time to get used to the environment.
Players don't also score that much in Europe. Averaging 20-25 is very good. It's not a one man game.... far less iso and more ball movement. Less space to work with 2 pt FG. Doubt Iverson is quick enough to take it to the hole either.
15 pts is decent for 25 minutes of play. Don't hate on a legend.
