I'm not sure why I'm wasting my time responding to this because you've clearly got some very expensive homer glasses on if you honestly believe that, but I can't help myself. Even if this was the trade deadline and JVR was a pending UFA, you'd still be adding to McCarron in a trade. Given the fact JVR's got two years left on a great contract, I doubt McCarron is even good enough to be the main piece in that deal.
I get that he's your best forward prospect and all, but that doesn't magically make him a blue chipper and anything close to JVR's value. Again, I realize I'm obviously not going to convince you here, but go ahead and start a poll about who has more value between JVR and McCarron if you want to see how far off you are on this one.
