An 8 knot crosswind at 130 knots would not cause this accident by itself. A combination of the crosswind and .16 EPR more L reverse and nosewheel not yet on the runway probably will be the cause.
I think everybody agrees using reverse thrust will increase the downwind drift on an icy runway if the plane is angled into the wind but being blown to the downwind side. In this case this didn't happen. The plane left the runway on the upwind side so the plane just had to be straightened out to stay on the runway.
