I'm concerned about how this defense will look in the second half of the year.
Ware and Spencer are undersized for their roles, and will be taking on more blockers on a down by down basis. By the second half of the year, I wouldn't be at all surprised to see both of them performing at significantly less than 100% effectiveness. While Hatcher doesn't have the size deficiency, he will be playing more snaps this year than he has played in his career. As the depth across the line is not good, I think these guys will be playing way to many snaps, and will be worn down if not injured by the end of the season.
As long as either Hayden/Hatcher can tie up two blockers, they will be able to hold their own against the run. With Lee and Carter playing in space, they will clean up against the run.
