The following calculations are based on science.
Imagine a 2011 Rangers team where Cruz, Kinsler, and Hamilton play full seasons without injury. I have projected each Ranger starter's WAR to 160 games. And assuming we do not sign a single free agent, and each player performs as they did in 2010, the Rangers amount to a 51.6 WAR team without even resigning Cliff Lee (factoring in a 0 WAR player at DH, C, and #5 SP, because I'm being real here).
Now imagine that same team with a few off-season additions... We'll be reasonable. Give me John Buck at C and Vlad Guerrero back at DH. Upped to a 57.2 WAR team... not bad at all.
But what if this off-season goes really well? How about signing Cliff Lee, John Buck, and Vlad Guerrero? 64.3 WAR. We're talking historic at this point.
Lastly, let's go ahead and sign Cliff Lee while trading Derek Holland and co. for Zach Greinke. Then, instead of signing Vlad, let's move Face to DH and bring in Adrien Beltre to man 3rd.
That's right... your 2011 Texas Rangers will prove to be the world's first 72.5 WAR team.
