Joe Nathan-what to do with him

The Twins have an interesting decision to make with Joe Nathan he will be a free agent at the end of the season and alot of young guys in the bullpen that might be able to do the job. My opinion on this is if the price is right sign him because he is one of the top 3 closers in the game and pitchers like that are hard to find. Nathan will be 33 so what i would do is tear up this years contract and offer 4 for 48. i think thats a very fair offer and if he wants more i would get would i could for him but i would wait till the deadline because relievers are more valuable then look at what Texas got for Eric Gagne last year. But i believe that if Joe Nathan truly wants to stay with the twins he will take that and the Twins will have an awesome closer for the next 4 years. i would appreciate everyones opinion on this and i might have more this afternoon.
