It is still a long way until the 2016 NFL Draft. A lot of what we expect will change after free agency. It is my hope that the Titans address their offensive line needs in free agency, but that is yet to be determined.
An ESPN report from Adam Schefter today says that personnel executives expect the Titans to take Laremy Tunsil, OT, Ole Miss with the first pick:
If Tennessee remains at No. 1, NFL personnel executives said this week that there was a real chance the Titans would take Ole Miss offensive tackle Laremy Tunsil.
Schefter goes on to talk about the different trade scenarios that could present themselves for the Titans. A trade is the best case scenario, especially if it is with the Browns at #2 because they could get extra picks and still get the top player on their board.
Again, there are a lot of dominoes left to fall between now and the draft, but you would have to consider Tunsil the leader to be the #1 pick as of today.
