I still don't get the comparison to DD though - as a basketball player. Evans is multi-dimensional on offense. He can play PG through SF. He rebounds. He creates. He gets steals (although his defense is likely on par with DeRozan at best). He is more efficient. He has made steady improvements in his three point shooting while giving a sample size large enough to draw a conclusion (2 per game over 4 seasons).
I don't think BC dodged a bullet because DD and Evans are not in the same league as players (but character and injury history certainly help lower the spread).
