PHILADELPHIA – The frown on Michael Vick’s face emphasized how bitter the Philadelphia Eagles’ latest loss was.

Vick had one of the best days of his career with a personal high of 416 yards passing and 30 completions, added 75 yards rushing and two touchdown passes. It was all for naught as the Eagles lost their third straight, blowing a 20-point lead and falling to San Francisco 24-23 on Sunday.

“We’ve got to dig deep,’’ Vick said. “It’s right there for everybody to see what is taking place, how it’s been done, what hasn’t been done and what needs to be done.’’

Vick did about all he could, only to see the Eagles fall apart on defense in the second half. He was at his scrambling best and his one interception was tipped by DeSean Jackson directly to cornerback Carlos Rogers. His bruised right hand, protected by a padded pink glove, didn’t slow him a bit.
