Must be how the stars are aligning, but now this: ETonline reported a couple of hours ago that now Matt Lauer has told NBC his current contract will be his last. It ends December 2012, so don't start worrying about life in the morning without Matt just yet. I get into this in a column in tomorrow's Newsday, and I suspect ET is right. Here's why: Matt will have been in the gig exactly 15 years next year; his pal, Bryant Gumbel, left at 15, and so did Katie Couric. Indeed, 15 is the magic number. Could NBC prevail upon Matt to stay beyond that time? Sure! Anything's possible, but he does already make $16-17 million per year, the biggest salary in TV news. How much richer does he want to be, and will a couple more million help his golf game? Questions only Matt knows the answer to.
