Should i trade Larry Fitz and Marshawn Lynch for Ronnie Brown and Matt Helback?

Absolutely not. Fitz is an elite receiver and Lynch could very well end up comparable to Brown by seasons end. Helback is on the downside of his productive years. No way you make the deal, especially since Leinart is a solid option. Plus you get a double dip for every Leinart to Fitz hook-up.
