As 49ers point out, Westbrook and Gore become NFL's top tandem since 2005 in terms of career yards from scrimmage, with a combined 14,438! I don't understand why people don't like this move? Westbrook will compliment Frank Gore. BW won't be a feature running back. They can also help keep eachother healthy. BW also understands pass blocking schemes well (Better than Anthony Dixon). It makes sense to me.
I understand the concern about his history of concussions too, but that's the chance you take!
