Marcus Lattimore concedes he's "not all the way back, physically or mentally" from his catastrophic college knee injuries. Lattimore's career-ending injury involved ACL, PCL, and LCL tears in his right knee. Lattimore concedes he "still lacks the first-step burst" and "explosiveness through the hole" that he possessed as a freshman. Even before the 2012 triple-knee-ligament tear, Lattimore tore his left ACL as a sophomore. Lattimore is an easy guy to root for, but remains a long shot to rediscover his past dynamic form. We'll monitor him closely in training camp, of course.
