Really glad to hear that Gronk shouldn't miss extended time.
If there's any question about his knee being sore, though, I'd sit him at least one week. When guys play and they are unsure about one part of their body, they overcompensate elsewhere and that can cause more serious injury.
The Patriots are going to grind out wins from here on out. Hopefully the defense will bounce back from giving up 30 points to Osweiler. I guess you can't entirely blame them considering the offense couldn't stay on the field.
