"Though Paxton is 32-years-old, he has just 750 innings of mileage on his arm, signaling that there should still be plenty of juice left in him." That's a rose-colored glasses perspective for a player with his injury history. I'd argue it's evidence that his arm never had any mileage to begin with. As a couple others have said: both. I don't think Odo and Paxton compare. Yes, Odo barely pitches last year but all signs suggest he is fully healthy, whereas Paxon would be a prove-it type contract.
