Yep. I didn't expect you to go PG/PG so Arenas was a great pickup. I'd certainly have snagged him had you left him behind.
I like yahoo's rankings, they're informative but only to a point. I only have two guys in the top 25, one of whom I just picked up. But I do have 7 in the top 50, so it works out ok. But you know all that from baseball. Sometimes a poorly ranked guy fills a hole for you in spite of his other stats. As long as someone else is picking up the slack. 4-5 guys that are free agents in the top 50 as well.
