Old Jacobs is still probably the best punch it in back in football. He's so big and strong, he probably will be til the day he retires.A million years ago, the Giants set like an all time worst for red zone productivity and their solution was to put Tiki and Jacobs in the backfield on occasion(not all the time and only inside the ten a few times). Ds couldn't stack the line to stop Jacobs because Tiki would run outside. On the very rare occasion Jacobs played a FB role, GL getting around him. Any focus inside made Plax and everyone else's life easier. It invigorated their GL offense and soon enough they weren't doing the two RB set anymore. Defenses just didn't fear them, their mentality was all wrong, and it changed everything in a good way.If Harbaugh wanted a spark, San Fran could certainly say GL to Ds and put Hunter and Jacobs in in a very similar fashion. I doubt he does.I don't think ya get creative with Jacobs, but just smash him into the Dline and wear em' down or get a tough first down or GL. For forever, Jacobs was an absolute nightmare in camp when he got a pass up the sideline. He was simply too fast or strong for any DB to tackle. He did it like maybe three times in preseason and maybe twice during his entire career in the NFL. Somehow the Gmen could never work that in and every DB was under absolute orders from the DC to never let him catch a screen pass there. Wayyy easier to swat a pass away or even make the QB look elsewhere than to stop Jacobs with a full head of steam. That was then though.As a main RB, he wore down Ds plain and simple. He wasn't that great with vision and moves and...but by the third or fourth Q wow did Ds look beaten up and worn down. The older he got the more he got hurt and was out with banged up knees and sore ankles and everything you could predict about an older RB that played a smashing style.I don't think he can do anything special anymore and didn't have much special to him before except his enormous RB size. That's all he's got now. He was slowish before and I never really thought he lost any speed like other RBs do. I bet he's the same speed. Right now he's got about the same draw as putting William "The refrigerator" Perry in or when a coach throws the FB a bone and lets him get a GL carry.Good luck to the D, we are running right at you, try and stop us. In the football world, being predictable and succeeding can breed a huge amount of confidence. Gibbs and Parcells both did this countless times during their career. It's arrogant, it's brash, and it'll wreck a defense's confidence to know exactly where the ball is coming and they still can't stop it. I bet Jacobs' value to San Fran will be more than the casual fan notices and that Harbaugh loves the guy.For FF, I just think some TD vulture at a rate like we haven't seen in years.
