I don't believe Vontae is near as effective as Revis presently but: a)he's probably further ahead of him going into their respective 2nd years, and, b)what Vontae may concede to Revis in coverage, the punishment he inflicts will linger longer in the WRs head. Long term with experience, IMO there's a good chance Vontae even exceeds Revis overall, becoming an equal in coverage, and superior in run defense and certainly in physicality.
