I get that Caldwell is a security signing, but he's not all that impressive when he is on the field and he'll not replace Decker as so many readily believe. We're talking about the same receiver that has been given the opportunity to be a starter in Cincinnati and he underperformed and if he was capable here, then could have easily been more effective when he was given a shot and yet, he still underperforms. Maybe Manning can coach him up, but all in all this was a depth/security move and with how free agency is playing out, Denver will likely be taking a receiver to replace Decker high in the draft.
