In a somewhat surprising move, the Denver Broncos on Tuesday afternoon released starting defensive tackle Sam Adams, one of the best interior run-stuffers of his era, but a player who made little impact for the team in its first 12 games of the season. It is possible, given Adams' resume and reputation, that another franchise could sign the 14-year veteran for the playoff stretch run. But having registered only nine tackles in 11 games in 2007, and having failed to deliver the kind of production the Broncos expected when they signed him as a free agent in June, it is also possible his long tenure could be in jeopardy. Adams, 34, has played with six different teams.
