Michael Irvin tells TMZ Sports ... he SUPPORTS Donovan McNabb -- arguing the QB belongs in the Hall of Fame but says he definitely AIN'T better than Troy Aikman.
Remember, McNabb made his case for Canton last week when he appeared on the "TMZ Sports" TV show -- and part of his argument was that his career stats are better than Aikman's.
-- McNabb has 37,276 passing yards, 234 passing TDs and 117 career interceptions in 13 seasons.
-- Aikman has 32,942 passing yards, 165 passing TDs and 141 career picks in 12 seasons.
