Look at it another way. I will never trust Oline evaluations of a team that started Noteboom at guard for a second season, after a disastrous first time around, and one who still has Brian Allen and Shelton as the backup centers. Allen was bad the first time he started. What made them think he was ready? It is reasonable cause to not trust the decisions regarding Oline.
I get that they are inexpensive but I think its beyond time to find a better backup or to train a guy like Anchrum to be the center backup. Even if they didn't draft a starting center a better backup option seems like a worthy need to address.
I would point out a few counter points here:
First, that could have been Kromers input and possibly why he's no longer here
Second, and more importantly since McVay has the final say:
In 2017, we started two below average offensive linemen in Sullivan and Brown. Brown was so bad that we just cut him a year later.
In 2018 we started two bad offensive linemen - Sullivan and Blythe.
In 2019 we started what ended up being three bad offensive linemen - but we were 3-0 to start the season, and the last five games of the season they played well. The Allen experiment ended.
In 2020 we started one bad offensive lineman in Blythe. The OL performed well for most of the season.
For probably 75% of McVays games as HC, the offensive line has performed really well. I point out that there's always a bad player on the OL in tandem with that 75% number because there's a method to his madness - could be mental aptitude for example.
The thing about that 25% is that the other guys get paid too - and sometimes you run up against a Khalil Mack. In those instances, the OL needs an assist. Pretty clear from out off-season moves that McVay wants guys who can help with that 25%
