Okay first of all, let's take the hyperbolic language out of it - nobody is saying we should trade away all our youngsters. But when you build a good to great farm, which we did, you need to spend some of it at opportune times and and keep the players you want to fill holes. We're at that time now.
I think a probable road block in this discussion is that you likely see Mayer as someone to depend on next year, like he is ready to man either 2nd or 3rd. I don't.
Right now I see us needing two bats. If we go out there with Mayer on a base I think we're asking for trouble. So if he's there or not, I still see us needing the same. So I don't have much issue in including him in some deals.
My personal preference would be to keep him and leave him develop further in AAA, but I'm fine with trading him for our needs too.
