The line has got all of it's parts back and added a few intriguing but raw reinforcements. I'd wager that they're more likely to be a decent line than a poor one and that they will get stronger as the year goes on.
RB - The Patriots have an excellent pair of backs and I suspect that they'll be able to add decent backups later today.
QB - They obviously will have another QB on the roster later today, perhaps Zappe and/or Malik. I'm indifferent on Zappe, I thought he could be a serviceable backup, but his struggles in preseason were real. I'll reserve the right to panic after I see who they sign today, and hopefully whomever it is won't play a snap this year.
