Carter may be BPA, but on top of that, there is nothing but evidence that the Kings don't feel like they have the guards they want yet. Drafting Colby Jones, Davion, the Ford 2 way contract, trading for Duarte, the frustration with Huerter. In that context, it's not that the Kings have too many guards, it's that they can't find the ones they want to keep.
To hear the national media guys tell it, they didn't think the Kings had the guard talent solidified either. Sounds crazy when they have Monk and Fox, but when Monk went out, the season tanked. When Fox has his mid season swoon and is a mere mortal, the record reflects it too. So...maybe they are onto something.
