Quarterback is a position that is the most important on the field. If you have a bad quarterback, your team won’t go very far. Or if you do have a good quarterback and he gets hurt you there’s no depth behind him, you won’t go very far either.
Depth might be the only way to explain the signing of Chad Kelly by the Colts. The nephew of star Jim Kelly is now on his second NFL team. He had previously been with Denver after being taken with the last pick in the 2017 draft.
