Robinson Cano was 30 years old and Albert Pujols 32 years of age when they received their free-agent contracts of 10-years, $240 million dollars each. But one should wonder how did Robbie get the same amount as Pujols?! I'm thinking the same thing. Let's compare them.
This is based on a prejudging that they signed both based on offensive production and career accolades through their age 30 seasons.
First, let's look at how many times each player has posted an OPS of over .900. This is the on-base percentage+ slugging percentage. Cano has done this 2 times in his career. Cano has played 9 season thus far. Meanwhile, Pujols has accomplished this feat an amazing 10 times in 10 years, so each year he posted an OPS over .900 and 8 years out of 10, he has posted an OPS of over 1.000. Just to put these numbers in perspective, the average Major Leaguer's OPS in 2013 was .714 and in 2010, when Pujols was 30, the average OPS that year was .728. Cano's OPS in 2013 was .899, just 185 points higher than the league average. While this is still a sign that Cano is a star, it does show when you look at Albert's numbers, they just don't stack up. Pujols' OPS in 2010 was an amazing 1.011, an incredible 283 points higher than the league average. It's also 112 points higher than Cano's 2013 OPS. So this is one evidence to how Pujols was better than Cano by a pretty big amount in their age 30 seasons.
Additionally, through age 30, Cano has 204 home runs and 822 runs batted in. Pujols had 408 home runs and 1,230 RBI's by this point in his Hall of Fame career. If you average these stats over the amonut of years each player has played, for Cano you get about 22.7 homers and 91.3 RBIs per year. This dwarfs Pujols' per year averages of 40.8 home runs and 123 runs batted in in at age 30.
Furthermore, through their age 30 seasons, Cano has had a carrer WAR, Wins Above Replacement, which tells how much more wins a player is worth than the average Major Leager, of 45.2. Whereas, Albert's WAR was an amazing 81.1. This means that through age 30, Pujols was worth a total of 35.9 wins total, or 3.59 wins every year over a 10-year span. Especially considering Cano was worth 4.3 wins more than Pujols on defense, that means that just based on offense, Pujols is miles away more worthy than Cano.
Yo add on, Cano's career on-base percentage at age 30 is .355. Pujol's on-base percentage at that same age was .426, which means he was not only a force with his power, but an on-base monster as well. While Cano's on-base is not shabby, it's nowhere near Pujol's, so I belive this is proof enough that Pujols was way better than Cano through their age 30 years and that Cano isn't worth his contract.
