Nike went to court Wednesday to prove that Reebok is not a lock to promote Jets quarterback Tim Tebow. Nike Inc. claimed in a lawsuit in U.S. District Court that Reebok International Ltd. has used Tebow's name on Jets-related apparel without permission since it was announced last week that Tebow was traded from the Broncos to New York. The Tebow trade occurred just before Nike replaces Reebok on Sunday as the supplier of NFL team uniforms.
