Once Jonathan Goodwin, Carlos Rogers and Donte Whitner are released next year (Ahmad Brooks and T. Brown possibly as well) and Justin Smith retires, the team will have enough money for Aldon, Kaep, Iupati AND Crabtree...
The team has players in place to replace those names either right now (Culliver and Kilgore/Looney) or via development (Carradine and Lemonier) and also have draft options in 2014 to fill the void.
I personally think the team would be making a huge mistake by letting Crabtree walk.
If we're talking changeable components to an offense or the value of each position, in my opinion, Left Guard ranks below Wide Receiver.
