Who is likely to get more tackles this Sunday? Kirk Morrison or David Harris?

Many people probably do not know who either is. But Kirk Morrison plays middle line backer and he plays against Green Bay this week. While David Harris is filling in an injured player. He plays on the Jets versus the Browns this week. He is in a 3-4 system. It is hard to tell who is going to get more fantasy pts. But tackles are a consistent point bases. So i figure who has the best oppurtunity to get more pts? Both teams they play run the ball about the same. What do you think?
