I'm not sure about a hot Buxton start. Sure, he's got 3 HRs in 6 games, but that's pretty much all he's done. 10 Ks in 26 PAs isn't great and is double the number of hits that he's got. I know the OPS is nice, but I'd like less feast or famine to call it a hot start.
It's early yet though. I'm not worried about him getting going.
