Cobb adds an element of quickness and elusiveness to the Packer offense that nobody else on the current roster can provide. TT has done a nice job of finding receivers whose strengths complement each other. Letting Cobb go would deprive the offense of one of its most explosive components. I have no idea what Cobb would or wouldn't be willing to consider for a second contract, but assuming his expectations aren't unreasonable I expect TT makes sure he stays in GB.
