Few know Candlestick Park and how the rain might affect conditions there better than Jerry Rice.

The 49ers' legendary wide receiver, now an analyst for ESPN, said that rain –- which is in the San Francisco forecast from Thursday through Sunday -- will likely turn the NFC Championship Game between the Giants and 49ers into more of a running game. And if that is the case, he favors the Niners because he says Brandon Jacobs needs to be tougher.

"That goes to San Francisco," Rice said on SportsCenter, of rain favoring the Niners. "I like Ahmad Bradshaw, I like Brandon Jacobs but I feel like Brandon Jacobs is a little bit soft."

"He can't get away from a defender," Rice continued. "This guy is 265 and it upsets me when I see him get tackled by a guy that's like 190 or 200 pounds."

Jacobs is scheduled to talk to the media on Thursday. Jacobs rushed for 571 yards and seven touchdowns this season. He ran for 92 yards against the Falcons in the Giants' wild-card victory and had 22 yards on nine carries in the win over Green Bay on Sunday.

"I'm sure he is going to be looking for me," Rice said laughingly.

As of Wednesday afternoon, the forecast in San Francisco called for a 90 percent chance of light rain on Thursday followed by an 80 percent likelihood of morning showers on Friday, according to Weather.com. There's a 30 percent chance of showers on Saturday and Sunday.

Rice said he had to focus even more when it rained during Niners home games.

"It is going to be different because you have to have a different mindset," he said. "I remember when I was a young receiver, I would always look outside the blinds when they predicted rain. If it was raining outside, I had to get focused because the ball was going to be a little bit more slippery."
