Keeper league trade advice needed.

I have been offered Vladimir Guerrero for John Lackey. What do you think about this proposed trade? This is my current roster.

BN-Fernando Rodney (Det-RP) 16:3
BN-Carlos Gomez (MIN-OF) 17:3

I would do that right now.

Lackey may not pitch for awhile.

Tough one. Vlad is on the decline and Lackey is hurting. I think your offense looks better than your pitching, so I'm not sure I pull the trigger on this deal.

Maybe see if you throw in Choo if the other team would throw in a SP?

He ended up trading him to someone else for Marmol. I did waive Chris Perez and picked up Rich Hill and Tim Hudson and put them on the Dl. I still have 1 DL spot Left that I can put Lackey on. This would allow me to pick up 1 more player. I did also picked up Billy Wagner. This is my Roster now. Does this look more balanced? What does anyone think of those moves?

I think Wagner is done.

Wagner certainly won't pitch this year. waste of a dl spot.

I have been offered another trade. Ryan Ludwick and Jair Jurgens for Joe Nathan. What does anyone think?

I was also offered Chris Carpenter and Rick Ankiel for Joe Nathan.

No on both. Keep Nathan- he is your only reliable source of saves. I would actually be trying to obtain another closer or look on the waiver wire for saves.

I just dropped Billy Wagner and picked up J.P. Howell. This is my roster now. I am wondering if I should get Phil Hughes who is a free agent.
