Well, this and many other reasons, I’m sure.
Now… I must note that the following discussion does take place regarding a league in which Kirk Hinrich and Larry Hughes were (until recently) fighting for a starting SG spot while a superior talent (unfortuntely, Ben Gordon) didn’t even enter into the picture. That said…
Does Terry Porter realize that Grant Hill is better than Matt Barnes? I know he wants to stabilize his second string lineup, but, does he also realize that he’s screwing me as fantasy owner over? I just drafted Hill (and I did look at Barnes before making the pick), and now you’re telling me that instead of the nearly 32 minutes per game he had last season, he’ll be lucky to clock in at anything near that because Matt Barnes is younger and not as good?

So who would you want in the game?
That’s what I thought.
So, come on Terry Porter: Skeeter/Obama 2012 (aka Epicte’s team) already had the #1 pick. He doesn’t need this sudden burst in value from Matt Barnes. I, however, who took Grant Hill in the 9th round, do need him to shoot his high percentages, and score some points, and get some steals.
For anyone else still looking for draft advice: I believe it’s time to bump Hill down a few notches and move Barnes up a corresponding number. I’d still go with Hill over Barnes because his percentages are that much better, and they’ll probably end up with around the same amount of playing time since Porter does need Hill in the game, but unless Barnes starts shooting a ton more free throws, his 74% (career 70%) won’t really hurt you too much, and they’re fairly comparable in stats that don’t end in “entage.”
