I am in a 24 team keeper league and I have been offered this:

I get: Harper Tyler matzek

I give: Beckett Archie bradley

You have to have 6 pitchers in my league and my pitchers so far are greinke Beckett, nolasco, hocevar, matusz, and navy guerra. You have to have 3 outfielders in the league and I have kemp, rios, and andres torres. If I made the trade my 6th starter would have to be homer bailey or kevin correa... Should I do the deal? Or I could do the deal and then trade Shelby miller for a Starting Pitcher or closer so my last pitcher wouldn't be bailey... Please leave in comments what kind of pitcher I should target on return for miller.

Another reason why I didn't accept the trade immediately is because I think my team can really compete this year and losing Beckett might hurt my chances... Please help me and any comments are appreciated...
