Eagles going OT at No. 4?

Even though the Philadelphia Eagles won the first big battle of the offseason -- securing Chip Kelly as their next HC -- the war is far from over.

Should they sign Darron Thomas away from the Calgary Stampeders of the CFL? -- but there's also that sticky problem of the offensive line.
