My thinking is this:
Essentially, Wallace could be the 4th receiving option in this offense, behind Welker, Gronk & Hernandez. then, if you factor in Lloyd...does this team need Wallace? Yes, they need a burner, but a draft pick might be a better idea.
The "4th option" stuff is nonsense, and the people making the "4th option" argument should all take a refresher course in football 101. It's not the number of passes, or even targets, that will be important with a guy like Wallace. It's the way he impacts the opponents. Every Patriots fan should have learned that in 2007 when Moss set records but, just as importantly, completely opened up the field for the rest of the WR corps.
Forte is a sweet runner & a receiving threat out of the backfield. BJGE was solid, but let's be honest- he was a product of this offense. A Forte could make this offense an all-timer.
The Patriots got more than 5 ypc from Ridley last season. The Patriots went to the Super Bowl, at 16-0, with Maroney running the ball in 2007. You don't need Forte, you need someone who can be successful in his runs. That's the system the Patriots play.
Take a look at Football Outsiders data on RBs. Notice that, even with a down season and had a very mediocre DVOA, BJGE finished 6th in success %. Meanwhile, Woodhead, who struggled early post-concussion and didn't have enough rushed to qualify to certain category rankings, still finished with a DVA of 25.4%, which would have put him among the best in the NFL had he been eligible. That's because, as you noted, it's about the running system in New England, and not about the back.
And the offense was an "all timer" type of offense this past year, if you're looking at points or yards.

The league is going pass happy, I agree. All the more reason to run more. Zig while the league zags.
The league is going pass happy because the rules of the league essentially require that teams go pass happy. Two of the league's best runners, for years, have been AdP and Steven Jackson. That hasn't helped their teams to any SB rings or, for the most part, even to good regular seasons. Forte and the Bears have been 9-7,7-9,11-5 and 8-8 with Forte as the back. That "zig...zag" stuff is silly.
