derozen's first play off game. he was really nervous. now he's playing a lot better. harden has play off experience. he does not get an excuse. besides, i'm just curious myself to compare anyway.
http://www.basketball-reference.com is your friend. And I think your memory is a little off if you think his only problem was the first game. His best shooting game was game 2 where he shot the same percentage as Hardens game 4. Like I said earlier the only big difference is free throws. Derozan is leading all players in free throw attempts this postseason.
