Do any of you think Powe's 20 point game in the finals came out of nowhere? Of course not... he was playing at an extremely high level the entire year and if you couldn't see that you're probably blind.
Powe has been mediocre this year, but last year he was playing at a borderline all-star level on a per-minute basis. So it's easy to see the potential.
Big Baby, on the other hand, has always been below average and I don't understand what other people could possibly see in him.
Powe caught LA off guard. I loved his performance in game 2. But do you think he will ever be able to uncork 20 points again against LA, now that they know who he is?
Hearing Powe mentioned in the same paragraph with all-star level is a bit over the top. 
Baby can at least lean on Duncan, Bynum, big Z, Varajao, etc. Powe struggles a ton against physical 6-10+ dudes. Baby can pass and handle the ball better. Baby moves his feet better on perimeter D against the bigs with range.
I still think it is a close call between the 2. Powe is a better rebounder, scorer (they're equally bad scoring against the above mentioned names), and is ripped.
Caught them off guard?! You have got to be kidding me! He had 20 games in last years reg season that he scored in double digits. 4 more in the playoffs prior to his big game against LA. You may not have been paying attention to how well Powe played last year, but I guarantee you that Phil wasn't caught off guard that Powe could come out and play at a high level.
If all BBD is good for is to LEAN on these big guys, then let's just go out and sign some big fat guy that is 350 pounds. I guess we could just wait a few more years and BBD will be there...
BBD is a very nice guy, and is much quicker a foot than you would expect a fat man to be, but his "intangibles" that everyone seems to love are one of the biggest myths thrown out there we have ever had.
Give me Powe's ability to score in the post, excellent rebounding, ability to draw charges, and ability to draw fouls on guys in his post moves, and you can have the intangibles...
