When Watt was talking about playing with a herniated disc and all that earlier in the year I was surprised because, having experienced that myself, it isn't just something you  can shrug off and say eff it; if you don't give it rest it will continue to linger. The surgery confirms this for me. I never had surgery on my back and it still flares up every now and then. Surgery doesn't always work; will be interesting to see if this has long term implications on Watt's career.
