There are many extremely positive stories with rookies at camp, but the offensive line draft choices have looked like busts, with the possible exception of Mafi.
One could have read the tea leaves when Sow was playing behind jags during early camp, but now I'm hearing he's too slow to be a tackle. Might be time to cut losses and see if he's a guard because Jake Andrews is not looking like a beast either from what I've read.
The names Ferentz, Russey, Murray shouldn't excite anyone. Maybe Hines and Mafi develop, but the backups at both guard and tackle are suspect.
