The San Diego Chargers won 10 straight games going into the playoffs last season, clinched home-field advantage and a first-round bye, then completely tanked against New England. Some Chargers still shake their heads at the unfathomable mistakes they made that day, the kind of blunders they didn't make in going 14-2. So here come the Chargers again, having won six straight and 10 of 12 heading into their home playoff game against the Tennessee Titans on Sunday. Although he said he got over the New England playoff loss after a few months, LaDainian Tomlinson said the Chargers were a bit full of themselves last January as they were for much of the second half of the 2006 season. "Last year, the season we had, it felt so easy throughout the year, winning something like 10 straight," said Tomlinson, fresh off his second straight NFL rushing title. "You had to get to that point where we were kind of a little arrogant, and saying, 'You know what? We don't think nobody out there can beat us.' We won 10 straight. You can have a tendency as human nature to do that. We did that last year and we paid for it." "This year things have come tougher for us. We have really been in some tough games. We have lost some tough games, some close games, and we have had games where we just got embarrassed. So I think all that, you go into the playoffs with a newfound respect, somewhat."
