Greetings once again, 49er faithful! It is I, your trusty college football contributor bringing yet another round of prospects rankings - this time we’ll be focusing on the linebacker position. The future was supposed to be solidified with the additions of Fred Warner and Rueben Foster - with Foster’s legal troubles and ultimate release, though, San Francisco is left with Warner (who has shown a ton of promise) and...nothing else, really. John Lynch and Kyle Shanahan would be remiss not to look at the free agent market and draft class to shore things up. Here are some prospects who may find themselves in red and gold come 2019.
