Is No. 81 cursed for the 49ers? Since Terrell Owens left the team almost a decade ago, the number has brought no luck to its wearers

Anquan Boldin has worn No. 81 proudly and effectively for both the Cardinals and Ravens. Now he'll wear it in San Francisco for the 49ers. Is that a mistake? Since Terrell Owens left in a huff, no receivers wearing the number have had any good luck with it in a Niners uniform.
