I doubt Leinart will be on a single team of mine this year. Warner, on the other hand, might be. If I'm going to dabble with the Cardinals QB this year, I'll take the chance and simply pass on Leinart and take Warner later at which point said Leinart-lover will be

Why waste two roster spots when the gut feeling screams Warner? It's a gamble, but IMO if you want to waste another roster spot on a QB, do it with another one in the Leinart ADP range, then grab Warner later and you probably have a great value or a darn good trade option for you when/if Leinart goes to the sidelines (again).
