My point was your simplistic comparison.
Manu was probably the most consistent Spur this season when we needed him to produce when losing wasn't an option. He stepped up when the other big two were hampered at different times of the season. Manu's scoring is streaky, but he never disappears, and is always there to pitch in with critical plays. He's hardly passive like Odom is, even when his shooting is off.
Odom is a uniquely skilled player, who gives the other team match up problems, but his mental edge and leadership is suspect. He IS passive when his shot isn't going, and has a history of deferring too much. I think when Gasol came the defenses were easier for him, so he flourished. Plus he wasn't hurt this year, unlike last year.
Basically when things are tough (our Spurs defense--the pressure of shouldering the scoring load with Kobe), he tends to withdraw a little.
