With NFL training camps ready to begin, Week 1 lines are already available for eager bettors at BetUS and other online sportsbooks.

And if you have some insight or angles to play, you can find great value with the oddsmaker posting lines so far in advance.

It shouldn't come as a surprise that the biggest spread in the Week 1 odds at belongs to the New England Patriots. The Pats are a huge 15.5-point favorite in their season opener against Kansas City.

In Week 1 last season, the Pats torched the Jets 38-14 as a 6.5-point favorite. However, it may be more important how the Pats ended last season. In their last nine games last year New England went 1-8 ATS. Will the Patriots fly out of the gate again like they did last season or will they have trouble covering these double-digit spreads?

The exact opposite question could be asked of the San Diego Chargers. The Chargers also received a big spread to cover in their Week 1 game at . San Diego battles Carolina in Week 1 as a 10-point home favorite.

The Chargers started very slowly last season going 1-3 both straight-up and ATS in their first four games. But, once they finally got their heads on straight, the Chargers cruised to a perfect 9-0 ATS mark in their last nine games. That includes covering five spreads of 8.5 points of higher.

If the Chargers take awhile to get going again this season they could have trouble covering 10 points in Week 1.

Rounding out the big spreads at is the AFC's other powerhouse, the Indianapolis Colts. Indy entertains Chicago in a Super Bowl XLI rematch in Week 1. Since that Super Bowl the Colts have remained Super Bowl contenders, while the Bears aren't anywhere near as fierce as they used to be. That's why the Colts are a 9.5-point home favorite in their Week 1 matchup.

Betting on Week 1 games so early can be a good way to find great value in lines that could move a lot in the weeks leading up to kickoff. But, it can also be a big money-loser if the team you bet on suffers a setback or injury bug during training camp.

Remember that you may be getting great value in some lines, but you could also be in big trouble if something happens to Peyton Manning or LaDainian Tomlinson. Good luck and have fun with these early NFL odds.
