I keep hearing stories connecting Datone Jones to the read-option problem... honestly if Jones was in that 49ers game I don't think he would of changed a thing. In large part, while the DL wasn't doing a good job, it wasn't where the Packers were getting burned the most ether.
The Packers got burned the most on the edges where depending on the call an OLB, ILB or S where suppose to protect the edge and they all failed to do it at one point or the other. As they had to take on a block and at the very least hold their ground and didn't do it. Datone Jones isn't going to be playing those position.
What is more likely going to help the read option problem is
1) having a physical LB like Perry and maybe Bishop back.
2) Mike McCarthy talking about asking to DL to focus in too much on techniques and not enough on going out there and going fully 100% no matter what, screw the techniques just kick their @$$... and talked about switching that some. which I think has been a problem... with those DL you got to keep their energy and desire to keep @$$ up... and I don't think the DL has been on full since Jenkins left, other than maybe Pickett and Daniels... and while I'm a big fan of Pickett he just doesn't have much explosion or pass rush... though he's clearly the best run stopper the Packers have. And Daniels is a big limited with his size but he'll give you all he had on every single play... you got to love that.
3) and having the coaches focused on stopping read option type stuff it in the offseason.
