He tried this last work and seemingly everybody on his team except him went down in the playoffs (so no ring).
I would imagine Cousins could still be in the market for a 'prove-it' deal, but that it will be more in line with what JJ Redick did a couple of years ago. Get a huge one-year contract from a desperate team with cap space (the Knicks) and see how it works out. The dude has to go for the money if it's available this time.
