He took heat because he didn't double Owens. He didn't take heat because of failing to press TO.""Even the pass he caught over Nate Clements' head, there should have been help over there," Singletary said. "It wasn't just Nate. You have a post safety who needs to get over there and help, and he should've been sacked in the backfield for a loss." As far as physicality, he had this to say:"I don't think there's any other team this year, or maybe in the last couple of years, that played Dallas more physically (and) more sound than we did." He also said the following:Asked why the 49ers didn't double-cover Owens Sunday, Singletary said they didn't feel it was necessary. He said other teams effectively have jammed Owens at the line of scrimmage and thrown his timing off. Before Owens' 213-yard outburst against the 49ers, his best game this season was an 89-yard performance in Week 2 against Philadelphia.The 49ers planned to borrow the same game plan every other defense had used. On some plays, however, the Cowboys moved Owens inside to the slot receiver position, where the 49ers didn't have as many opportunities to slow him down at the line of scrimmage. On others, such as the one against Roman, the 49ers were thwarted by a weak effort."One guy just kind of reached out and rather than knocking the snot out of him, he just kind of touched him," Singletary said. "And (Owens) ran up the field and Mark Roman was chasing him after that."Notice how he said, even when they pressed him, they failed, because they didn't hit him hard enough. Guess what? You hit player's hard enough at the line of scrimmage, your most likely going to be successful as a corner.
