Logical and in my thinking since the word of the trade came out…Considering that there is a complete lack of consensus regarding which of the four potential QBs Carolina actually intends to pick (i.e. that there is no consensus standout among them), I'd say that's a really, really big "if".
And if they are so close together that any one of the four of them could be picked, then I say that's all the more reason for the Colts to stay put rather than sell the farm to move up.
One of the four will be there for the Colts at the 4 pick.
