SANTA CLARA, Calif. – The fact that the San Francisco 49ers are planning to play star pass-rusher Aldon Smith is neither surprising nor alarming.I know some people were put off when Smith played in Week 3, two days after his second arrest for suspicion of drunk driving in less than two years, and a day before he voluntarily went to rehab. We've discussed that situation. I think the 49ers allowed Smith to play because they thought he needed to be around the team and it was the best way of making sure he went to get treatment.
