Offensive line ranking shuffled … The buzz coming from NFL people around the Senior Bowl in Mobile has confirmed a couple of major changes in how the offensive line is shaking out that have been percolating for several weeks. For starters, it appears that Washington State OT Andre Dillard has emerged as the top LT prospect in this year’s draft class. Scouts had been just a little concerned that he might not have prototype length for the position but Dillard was able to check off that box during yesterday’s weigh-in and then went out and held his own in some epic one-on-one battles with Mississippi State DE Montez Sweat, an emerging top ten prospect in his own right, during Tuesday’s practice session. At the same time, Alabama OT Jonah Williams, the consensus top prospect at the position for some time, has seen his grade take a hit on concerns that he doesn’t have the length to play OT at the next level and may have to kick inside. Both changes are reflected in an updated GBN OT ranking and revised Big Board. One other big change coming out of Mobile reflects the rather meteoric rise of Temple CB Rock Ya-Sin who all that recently wasn’t considered to be more than a fringe prospect, but is starting to attract some late first round whispers. ya-Sin actually played at FCS Presbyterian for three years and only transferred when the school dropped down to DII. Ya-Sin, however, didn’t skip a beat in moving to Temple where he was among the FBS leaders in pass breakups this past season.
