Making a move up in the 1st round is never worth it, in my opinion, unless you can get an Andrew Luck caliber player. This year's draft class does not have an Andrew Luck caliber player. Ironically enough, next year's draft class will.
If the Rams waited at 15, they might have been able to get Lynch. Instead, they blew their future load to move up to get a QB that maybe be marginally better than Lynch to begin with. I wouldn't have traded the 2016 picks to move up...but throw in the 2017 picks (the 1st rounder will probably be Top 10) and you have a landslide deal for the Titans. The Titans will now be able to beef up their OL and defense. Terrific steal by Tennessee, who might very well have 2 selections in the Top 15 and could, if they wanted to, trade out of one of those spots and add even more quality depth.
