BETHLEHEM, Pa.

When DeSean Jackson rolled into the Philadelphia Eagles’ training camp on Monday with his agent and his holdout in tow, it provided a brief reminder that even a team that has seized the N.F.L. marketplace by the throat this summer must occasionally deal with the mundane realities of insufficient contracts and unhappy players.

But Jackson is also a stark example of why the Eagles’ free-agent shopping spree, which netted top-line players like cornerback Nnamdi Asomugha and defensive lineman Jason Babin, and stunned the Giants by signing receiver Steve Smith last Wednesday, is unlike ones most others (read: the Washington Redskins) have periodically engaged in with disastrous results.

Jackson and quarterback Michael Vick are the only 2 of the Eagles’ 22 projected starters who are not under contract for next season, said the team president, Joe Banner, and Vick has said talks are under way to extend his contract. Banner estimated that 26 of the 28 players who are likely to get the most playing time in 2011, including kickers and punters, are under contract at least through 2012, and some of them beyond that.

Last year, the Eagles captivated fans with young, explosive offensive talent. Now they have injected some of the best veteran defensive help available. Banner cringed at the suggestion that the Eagles’ mind-set might best be described as “all in.”
