I totally agree they're not adding much, in fact overall they're going to be subtracting some WAR. But the payroll will in fact be higher - keep in mind that the cap is increasing from 178 to 189. It just illustrates how absurdly high the cost of 'veteran talent' has become.
We're now at the point where a solid #5-6 hitter like Napoli signs for 16 million a year and we're applauding it.
