Obviously, the need was there. They needed to have a veteran running back who can pass block, and who can be a short down back. And Jacobs fits that mold perfectly, and knows the system better than anyone else.
I'll say this: I certainly don't hate the move. However, I won't say I love it, and I'm not even sure how much I like it. My view probably is influenced mostly with how much of an douchebag Brandon Jacobs can be in general. I know his teammates love him, but I certainly don't. I love to see players play with emotion, but Brandon Jacobs takes it to the level where he just comes off as a jerk. He hasn't always had the smoothest relationship with the fans or media, either.
Obviously, none of us saw how he looked in the workouts, but he's been out of the game for basically 2 years. Who knows if he's in a shape to take over a meaningful role in an offense. And it's not like he was firing on all cylinders in 2011, either. He struggled to average 3 yards a carry in some games. Now yes, that o-line in 2011 wasn't necessarily the greatest at run blockvery ing, but still, he had clearly lost a step. Then he wondered why he was losing carries. This is opposed to someone like Michael Turner, who despite clearly losing a step last year as well, still was able to get 10 touchdowns. Brandon Jacobs hasn't scored 10 touchdowns since 2008.
I understand the move, and the reasoning behind it, and I understand that they didn't need a superstar. Like I said, I don't hate the move, but I think there were better options. Especially if Wilson's fumble problems creep up again, they need someone to step in and fill in for him after Coughlin benches him again. I do question whether Jacobs can handle that.
