Higgins does not have the skillset to play anywhere on the field, he honestly is too slow to play inside and get any type of separation; his skill set is more for outside work.
Versatility and being able to go over the middle, play outside and adjust your routes based on the D look requires very versatile players. Higgins is not all that versatile, frankly there are better prospects ahead of him when it comes to the tier 2 guys and not one of the tier 2 guys will be BPA at 22, that still appears to to be CB. So no, I challenge the thought that we need a traditional X WR, we need players who can catch the ball and are very versatile in their routes
