We report a numerical investigation of localization in the SU(2) modelwithout diagonal disorder. At the band center, chiral symmetry plays animportant role. Our results indicate that states at the band center arecritical. States away from the band center but not too close to the edge of thespectrum are metallic as expected for Hamiltonians with symplectic symmetry.Comment: accepted in Proceedings of Localisation 2002 Conference, Tokyo, Japan (to be published as supplement of J. Phys. Soc. Japan
