The Cubs shouldn't sign Pujols because then my "Cardinal fans take it in the Pujols" joke would no longer be funny. And in fact, it would be Cubs fans that like Pujols. Uh oh.
Just kidding.
I wouldn't give him a 10 year deal. I'm not sure who said it, and now I can't even find the post because I'm Special person, but whoever said give him a little more money for an 8 year deal, I agree with. Give him like 32 mil a year for 7 years or 30 for 8 and see how that goes.
Pujols for sure has about 4 really good years left and I can't see him declining extremely significantly over the remaining 3-4 years of a deal.
But seriously, my Pujols joke not being funny any more is the biggest problem with the Cubs signing him.
