As I've tried to make very clear here, I strongly believe the Titans will be spending a high pick, possibly as early as the 10th pick in the first round but in any event no later than the third round, on a player they intend to compete for and win the starting right job position. Among other things, that player will have to be able to block J.J. Watt.
There are three offensive guards that are generally considered to be selected in the first or second rounds: Jonathan Cooper from North Carolina, a first-round prospect; Larry Warford from Kentucky, a second-round prospect; and Chance Warmack from Alabama, a first-round prospect. To get a better feel for what the Titans might do, I watched the available videos of those players and tried to assess how I think the Titans might view them as possible fits.
I should stress that this is decidedly an amateur evaluation. The finer points of offensive line play and hand technique are beyond my ability to competently evaluate. Other people are good at evaluating these things, and you should listen to them. If, for instance, my Football Outsiders colleague Ben Muth says something that contradicts something I write in this post, he is right and I am wrong. Further, in evaluating these players I was looking for a right guard. Warford is a right guard. Cooper and Warmack are left guards. Right guards do not necessarily have the same responsibilities as left guards. To some extent, I'll feel more comfortable in my evaluation of Warford's potential for the Titans than I will for my evaluation of Cooper or Warmack, simply because he plays the position they're looking to fill and does a lot of the same things.
