Should I dump Jimmy Rollins For Troy Tulowitzki?

I picked up Rollins in two leagues and I am trying to get him in a third. Look what is happening with these young guys that have a hot start. Guys are depending on them and dropping the veterans. Rollins will hit .275 this year and steal 40+ bases. Tulo is a pretty good SS but still isn't as reliable as Rollins. These young guys who started hot, will not end the year hitting .400. They are getting picked at an inflated value and the value can only drop. Rollins on the other hand is being picked at a bargain price. Just like the market "buy low and sell high". I feel the same about Young and Pedroia. Dump Jimmy if you want but a guy like me is going to gobble him up and make you pay in the long run.
