Should I start Willis McGahee week 1?

Willis McGahee could have a good game this week if he is healthy enough. The Ravens are playing the Bengals and the Bengals defense is horrid. So if he plays the whole game he may have pretty good stats. Also Kevin Smith is gonna be the starter in Detroit and they are playing Atlanta who doesn't have a very good defense either. I honestly expect Kevin Smith to have a pretty good rookie year as long as the Detroit line can hold up. Good sleeper pick.
