Patrick Willis - the best MLB in football?

As I was watching the New Orleans-San Francisco game, I was very happy to see the Saints win. But what was very exciting to watch was the play of Patrick Willis. He made plays all over the field, was good in p coverage and is very strong against the run. He is not just a sideline-to-sideline LB, he's an all over the field LB. Is it just me, or does anyone else believe that he has quietly become the NFL's premier MLB? Ray Lewis is still solid at 33, but not the best anymore in my opinion. Urlacher? Still strong, but doesn't have the range that he used to have. What do you think? If Patrick Willis isn't the best MLB in the league right now, who do you think is?
