  After the recent discovery of a 125 GeV Higgs-like particle at the Large
Hadron Collider (LHC), it is crucial to examine its role in unitarizing high
energy W_LW_L scattering, which may reveal its possible deviation from a
Standard Model Higgs. We perform an updated study on WW scattering in the
semileptonic channel at the LHC, improved by the recently developed W jet
tagging method. The resultant statistical significance of a
Strongly-Interacting Light Higgs (SILH) model is about 20% larger than that
based on the conventionally "gold-plated" dileptonic channel, while 200% more
signal events are retained. This allows the discovery of an SILH model if the
signal strength is 100% (10%) of a pure Higgsless model, using about 40 (3000)
fb^{-1} data at the 14 TeV LHC. Meanwhile, the excellent sensitivity to the
anomalous Higgs-W boson coupling makes semileptonic WW scattering an important
complement to precision measurements at the Higgs resonance.
