First of all, I completely misread the OP (though it says "2016" right there in the title) and assumed we were talking about whether or not to pick up his 2017 option, hence my reply. I did support picking up the 2016 option and still believe it was the right call.
Other than that:
-While Price and Buchholz are currently sporting similarly ugly ERAs, delving into more advanced stats would suggest that Price has actually pitched much better than his ERA would indicate (similar to Buchholz last April), while Clay's peripherals are scarier than the ERA.
-People's perceptions of the two are rightly colored by the fact that Price has a lengthy track record of ace-like performance, while Clay has never managed this over a full season and has instead burned us time and again.
-I might have missed it, but I don't think anyone said anything remotely approaching "jesus christ clay sucks. DD is an idiot for picking up his option. clay is a bitch"..? Everyone realizes it's early and patience is called for.
