Mundane stuff to watch, right? Nothing to gain from it beside an informal roll call? Its almost all reporters get to see now that training camp is over and media access is limited. To Jerick McKinnon, those warmup sessions mean so much, because he could not partake in them the past two seasons. Two years ago today, McKinnon tore the anterior cruciate ligament in his right knee. It was a stunning blow, the weekend before the 49ers season opener and his debut as a high-cost, top-of-the-market acquisition. What did he miss, beside a franchise that endured many more woes and injuries (see: Jimmy Garoppolos ACL tear three weeks later) before bouncing back to reach last seasons Super Bowl?If I had to pinpoint all the small things. I really like the way everyone gets going in the warmup line, so I probably missed that a good amount, said McKinnon, regaling the energy and hype those seemingly benign warmups offer. McKinnon practiced only a few days at last summers training camp before requiring a follow-up procedure on his knee, landing him on injured reserve a second straight year. And now?Shoot, I feel good, McKinnon said after Mondays practice. The last two camps, I didnt make it through, so to make it through this one, it definitely feels good. The whole way through has been a smooth process and the staff has been working with my on little things through the rehab process to keep up my body maintenance. Im happy be here and make it through the last day of camp. As you can sense, there is no trepidation in his voice, unlike last year, and even though he is still nearly two weeks away from donning a No. 28 jersey in an official, 49ers game. His role? He would have been the undisputed, multi-threat workhorse
