I'm surprised that the Pats brought both Munford and Murray back. As I stated, Murray because they already had Jaimes and Rupcich on the PS.. Munford, I can understand signing to the 53 because that was the only way to get him from the CLE PS. They likely went with him because he's spent about a month with the Pats, so he has a bit of familiarity.
Whether they are stiffs or decent depth O-linemen going forward remains to be seen. Losing 2 starting O-linemen in the same game puts a strain on a team.. How the Pats recover going forward will really speak to the quality of the team.
