19. Bobby Massie
One of the players on this roster who improved the most from last season to the next year would have to be Bobby Massie. Massie is not necessarily a fan favorite and has never been a strong point to an offensive line.
However, he has always been good enough. Last year, he maintained his status, and then some. With Kyle Long injured and a rookie at right guard, he became the third best lineman on a playoff offensive line.
The Chicago Bears locked Bobby Massie down to an extension after he played so well in 2018. He now is locked in as a solid right tackle which jumps him from fringe top 30, to inside the top 20. That is a good jump for Massie.
