Here's the thing why Wynn coming back is so important. It's not like he's the instant savior. But the OL will improve incrementally. Having a guy out there with the skills to block his man one on one, makes EVERYONE else's job that much easier. Remember we aren't talking about making THAT much of an improvement. Keeping Brady clean even a second longer widens the route options that much more.
BTW- even WITH Newhouse, the Pats pass protection has hasn't been all that bad this year. Brady has been sacked just 17 times. That's 4th fewest in the NFL (Dallas at 12 is the best) And the 51 QB hits is fewer than the 54 Dallas has allowed with their all world OL.
The run game is another issue all together. Losing, Gronk, Devlin, AND Andrews were HUGE hits. It's not JUST the OL that creates success or failure for the run game. Then when you add Wynn, this is over half your run lane creation. So just having Wynn coming back is not going to SOLVE the running game issues, though it should improve it...incrementally.
So in the end, I see Wynn's return as very important to the Pats offense, but not the "answer" to all the issues. But that being said I think the answers ARE out there. In other words, I think the "talent" we have on hand is enough to produce something close to the kind of offense we've become used to as it develops over the last 6 games of the season. It would seem at this point we are 14 games into our season long PREseason. Hopefully, come the start of the REAL season in January, we will have this offense thing figured out.
