The most important unit for the New Orleans Saints (or any team) need to get in the swing of things quick in order for the Saints to keep trucking ahead.
Let's not get it twisted, the New Orleans Saints are 1-0, and got the always big opening day win. However, that isn't to say the Saints were perfect. The most important unit on any offense (or honestly any team) has room to grow, and if they do, watch out.
Games are won and lost in the trenches. As such, having a solid offensive line is absolutely crucial to the success of any football team. Look at the Philadelphia Eagles last year, or any great team throughout history. The Saints may have won in week one against the Tennessee Titans, but it was by a score of 16-15. Of course a win is a win, but it didn't have to be that close.
Derek Carr was running for his life for a lot of the game, and it took Jamaal Williams a pretty good while to get going. It does have to be stated however that this isn't meant to be a complaint. The fact that the Saints were able to get the victory despite the offensive line against a solid team is encouraging to what this team could be.
If they're to get there though, the offensive line is the key to unlock their true potential. It isn't like the group is devoid of talent either. Ryan Ramczyk is an absolute stud, and Cesar Ruiz was just rewarded with a contract extension for the work he put in this Summer. Trevor Penning was a first-round pick, and is still getting in the swing of things.
The main point here is, once the offensive line of the New Orleans Saints play like they're capable, the sky is the limit for this team. This isn't a criticism, just observing what has to happen, and should happen, for this team to reach the next level.
