The Cardinals ended training camp with a full-fledged quarterback controversy and one very irritated Pro Bowl receiver. Despite that, the overall mood was optimistic because players and coaches are confident they have the talent to win and contend for a playoff spot.

Most people know about the offensive talent. Running back Edgerrin James, receivers Anquan Boldin and Larry Fitzgerald and quarterbacks Matt Leinart and Kurt Warner are household names.

But the biggest upgrade has been made on defense, where the additions of players such as linebackers Clark Haggans and Travis LaBoy should make a big difference.
