The challenge is evaluating an OL that was bad at all 5 positions. This made it impossible to separate one player's suckage from the suckage of the unit as a whole.
Moses is on board, Bradbury is next if you're to believe the entire media. You lock Onwenu back at his natural position, with an OC who maximized his talents, now you have above average players at 3 OL positions.
If, hypothetically, you drafted a day 2 starter at LG, placed Lowe at LT, and let everyone else fight it out for 4 roster spots, you would be better. Good enough? I don't know, but certainly better.
