Hartline and Welker are not the same player. Hartline does play a true flanker position and at the #2WR position he'd still be split wide. He hasn't been the slot guy. Welker has always been that slot guy. Welker has made his bones scorching nickelbacks and blowing apart zone coverages. He hasn't been out on the sideline beating press coverage. Hartline has, which is why he's easily worth 6.5 million bucks. Guys that can beat press coverage and get open are worth paying.
