Pittsburgh Steelers coach Mike Tomlin expressed anxiety over the sexual-assault allegation leveled at quarterback Ben Roethlisberger, telling NFL Network's Jennifer Allen on Saturday, "I'm highly concerned for our franchise and for Ben personally." Tomlin didn't want to say too much about the situation, acknowledging that police in Milledgeville, Ga., are still investigating a 20-year-old female college student's accusation against Roethlisberger. "My concerns are many, but I think at this time it's kind of appropriate to watch these things and let these things run their course," Tomlin said after arriving in Orlando, Fla., for the NFL Annual Meeting, which starts Monday. "I think it would be inappropriate for me to have strong feelings one way or another with the investigation being ongoing and so forth. Like everyone else, you watch these things unfold."
