(Sports Network) - The past two drafts have given Oklahoma City an improving nucleus to work with.

Kevin Durant, Jeff Green and Russell Westbrook bring youth, energy and most of all talent to the Thunder franchise.

General manager Sam Presti has quite a bit of cap space to work with this offseason and plenty or work still needs to be done. Depth is a big problem at virtually every posistion and power in the frontcourt is in short supply.

Oklahoma City has two first round picks to work with, the third overall and No. 25. Arizona State guard James Harden may be the most NBA-ready player in this draft and should be a steady and consistent wing player very early in his career. He has gotten a lot of attention from the Thunder and Washington Wizards. Now, the Grizzlies have put him in the mix and are apparently enamored with what a three-man rotation of Harden, O.J. Mayo and Conley could do. In the end, I think the Grizzlies go big, leaving Harden to team with Durant and Westbrook in Okie City.

At 25, expect the Thunder to take the best player still available. North Carolina star, Wayne Ellington, a great college player that projects as a 20- minute guy in the pros may be the answer there.
