Hey clumpy...
What about 3 yrs and 12 mil, 6 mil SB...
Year 1 1.5 BASE, 2 prorated SB
Year 2 1.5 BASE, 2 prorated SB
Year 3 3 BASE, 2 prorated SB
Now, by Year 3, we'll have a good idea of how PW is performing. We can cut him and take the 2 mil in dead money (not too bad), or toss him another mil to restructure for a Year 4. Years 3- 4 would then look like this...
Year 3 1.5 BASE, 2.5 prorated SB
Year 4 1.5 base, 2.5 prorated SB
