Rummaging through this year's upcoming RFA's, there are interesting SG/SF RFA's that the Nets can grab if they want to go that route: Barnes, Fournier, Schroeder, Clarkson, Ross, Galloway, Canaan, Crabbe, and Burke.
Depending on their salary cap situation, they can offer over payments to a couple of them and hope that they make the leap. Lopez, if his health problems are in the past, is an All Star caliber player and should be built around unless an excellent trade package is offered for him. If the overpaid players don't pan out though, the next few years will be miserable.
