The 49ers aren't showing interest in Eagles quarterback Donovan McNabb, according to ESPN's Adam Schefter. "It's still hard for me to understand why San Francisco wouldn't ship one of its draft picks -- maybe the second -- to Philadelphia for Donovan McNabb," Schefter wrote. "To the best of my knowledge, unless people are bluffing, the 49ers are not interested in trading for McNabb. But put McNabb on the 49ers' roster and they become instant favorites to win the NFC West and as formidable as anyone in the NFC. Would really love to see that move, but that's not going to happen." The Raiders have emerged as the top suitor for McNabb.
