Another postponement in the often delayed trial of Washington Redskins safety Sean Taylor in a Miami court came on Monday, with the new trial date of July 10 likely to be about three weeks before the opening of training camp. A continuance, the seventh delay in the case, was granted at the request of the Miami-Dade State Attorney's Office, which introduced a new lead attorney, Abe Laeser , after prosecutor Mike Grieco resigned nearly a month ago.
