I saw the same article and rolled my eyes a little bit. The other thing that same writer forgets is that having a player like Lowe provides valuable depth and starting experience. That's massively important, and he seems to forget Lowe's real role. It's not exactly like teams have multiple elite left tackles on their roster.
Lowe really wasn't meant to be a starter for a full year last year. He was still a developmental player, and in all honesty, he was the bright spot between the two tackles given how much better he did perform at a more difficult position compared to Demontrey Jacobs. The kid worked hard and did what he was asked, and was serviceable enough where they survived the year.
People also forget that Lowe was hurt when he stepped in for Okorafor in week 1 after they swapped him out 12 snaps in. If Campbell were to get hurt and miss a game, I'd be OK with Lowe filling in for one or two games. He's just not a guy you want to see out there for a full season.
I feel like people forget that yes, you need an elite starter when it comes to protecting a quarterback's blindside, but you also need a guy who can at least step in if that starter goes down. Lowe has grown into being that guy, and honestly, good for him. Although again, I'd prefer he doesn't see the field, but if he's forced out there for a game or two, while it's not ideal, they could definitely do worse.
