Cassel (foot) has been traded to the Bills from the Vikings. The teams have also exchanged undisclosed draft choices as part of the deal. Well, if there's one team that's making headlines ahead of free agency it's the Bills, who made a big splash Tuesday with a trade for LeSean McCoy. The Bills lost out on Josh McCown, so apparently they'll go with Cassel (and maybe one other still undetermined guy) to create some competition with an unproven EJ Manuel in camp this season. Cassel, who missed most of last season with a broken foot after winning the starting job for the Vikings, heads to his fourth NFL team.
