"Only truly stupid teams or clubs ready to win a Super bowl would spend "big money" on a "disposable product" like a RB." a quote attributed to the Tuna prior to the 49er Seahawk game.
Chris Berman rolled the "disposable product" term around; aghast that Tuna was so brutally honest.
Much better to draft ten year players than 4 year players. Tuna pointed out that most RB careers are but four years long. By contrast the Seahawks left tackle will play ten plus years and make merely good RBs into great ones.
The Tuna said smart Teams don't want to and don't have to tie up big money in RBs. He said the Pats and Broncs won multiple Superbowls with merely good RBs that gained over a 1000 yards per year, behind good lines. And these successful teams used lots of RBs.
The Pats, for example, "the Team of the Decade" in Tuna's words, have used Antowain Smith, Corey Dillon, Kevin Faulk, Laurence Maroney and Sammy Morris and won multiple Lombardis. He also pointed out that Denver also won multiple Superbowls with T Davis and a host of other RBs.
Good organizations don't waste money on RBs; they spend it on long term players and end up with a greater number of better players and more talented Teams.
