I don't know where you're coming up with these lies. I also don't know what idiotic scale you're using to somehow claim that DeCastro is rated higher than Luck. He isn't. Draftable players are compared against one another, NOT compared to where they might stack up versus the current players in the NFL. You rate all the draftable players versus one another, and take the highest rated player available.
As K-9 has said numerous times, you take Andrew Luck because Luck is rated higher than DeCastro on an absolute scale of football ability. What K-9 is also saying is that in that same vein, you should also draft DeCastro over Bradon Weeden, because DeCastro is rated higher on an absolute scale of football ability.
You're doing nothing but being a dishonest liar by claiming that K-9 is saying to take DeCastro over Luck. He isn't.
