Inside Linebacker. UCLA. Myles Jack. 7. player. 42. The 49ers have a lot needs but their biggest need might be at inside linebacker. The retirements of Chris Borland and Patrick Willis in recent years depth at inside linebacker is a huge need. Myles Jack has played both outside linebacker and inside linebacker and is one of the best athletes in the draft. He could provide an excellent play making presence in the middle of the 49ers defense. <b> </b>
