You wouldn’t tender Santander because you don’t think he’s worth a 1 year 20mm deal (or whatever the exact value is) or because we can’t extend multiple players?
Having the benefit of replay it's obvious that it's not HJ's throw that is at fault, although as you noted he should have thrown it in to Gunnar when he reliazed he didn't have a 1 cut.
The bigger issue to me is Holliday learning to play 2b, he either froze watching the play or thought he had to cover? Either way he was no where near the cut line.
I'm a homer for Palmer but that was a really bad call blaming HK for missing the cut.
