Colt Following

In the AFC, two of last years strongest teams, New England and Indianapolis, are expected to lead the way. However, there are question marks over New England; they lost two key players in Teddy Bruschi and Ted Johnson, as well as one offensive and one defensive co-ordinator to boot. Indianapolis on the other hand look stronger than ever, the signing of defensive tackle Corey Simon has addressed a previously weak area of their team.

Last season Pittsburgh had the best record in the AFC, but crashed out to New England in the Championship game. The pundits don't rate them to do as well this season, but Sporting Index are currently predicting that the Steelers will make a Wild Card spot. If last year's rookie quarterback Ben Roethlisberger doesn't perform to the same level this season, however they could struggle to even make the play-offs. Of the other teams in the AFC, Kansas, Buffalo and Jacksonville may be in with an outside play-off chance, having recruited well in the off-season.

The two strongest sides in last year's NFC were Philadelphia and Atlanta. Both squads remain largely unchanged and they'll be the teams to beat again. Philadelphia's off-season has been plagued by controversy, with a series of bust-ups between quarterback Donovan McNabb and the Eagles Head Coach, Andy Reid. Could a lack of team spirit hamper their season? Atlanta should certainly be strong, the only question mark being over QB Michael Vick's passing ability.

Sporting Index has seen a lot of interest in Carolina in pre-season, with punters backing the Panthers by betting 'high' on Sporting's prediction of a Wild Card spot. Last season they had a lot of injuries and just missed out on the play-offs, so with a full squad to choose from they could certainly be a force. Although Minnesota traded away Randy Moss in the off-season, they've made some shrewd defensive acquisitions and could also be in contention.

Of the rookies on show this season, keep an eye on Tampa Bay's new running back Cadillac Williams. He rushed for an impressive 148 yards in Week 1, a record for a rookie making his debut. Much is also expected from Demarcus Ware of Dallas, in a pre-season game against Seattle this defensive end sacked a quarterback, recovered a fumble and intercepted a pass - quite a start!
