The rigorous on-shell T-matrices for NN scattering in the coupled channels 3S1-3D1 are briefly presented in the context of EFT(\notπ) with the contact potentials truncated at order Δ=4. The nonperturbative features of renormalization are highlighted and elaborated. A simple scenario for EFT power counting's and renormalization prescriptions is also presented with its consequences being roughly analyzed and discussed.
