I guess it's a matter of do you think Pujols will significantly outplay Hamilton the next 4-5 years to make him worthy of being kept. I really don't. Plus I'd rather be able to shell off money as quickly as I could. Paying 30 million to Pujols in 2020 isn't exactly keeping your team flexible (even though by then teams may be routinely rolling with 150 million payrolls). At least Hamilton is done after 5 years, while Pujols would only be halfway through his contract.
Really, it's just a big LOL fest over there. That's what you get for overpaying for 30+ year old FA's, Moreno.
There is no justifying the Pujols contract. LAA paid the Pujols "MVP premium" and that player is long gone. I still don't think it's a long shot to see Albert hit well (poor by his absurdly high standards) over the next 5-6 years.
