We model the tunneling matrix element squared as a Gaussian in the change of wavevector q parallel to the junction, $<|t({\\bf q})|^2>\\propto\\exp(-{\\bf q}^2a^2/2\\pi^2\\sigma^2)$. The $J^J_c(\\phi_0)/J^J_c(0)$ obtained for the s- and extended-s-wave order parameters (OP's) are consistent with the Bi$_2$Sr$_2$CaCu$_2$O$_{8+\\delta}$ data of Li {\\it et al.}, but only for strongly incoherent tunneling, $\\sigma^2\\ge0.25$.
