One of the highlights of Sunday’s Week 8 NFL slate comes from Empower Field at Mile High as the Denver Broncos host the Kansas City Chiefs in an all-AFC West dust-up.These teams met in the first week of the season, when the Chiefs dominated 31-10 at Arrowhead, a win that sparked a run of five straight victories.KC’s unbeaten start came to an end against Super Bowl champions Seattle last week, leaving them at 5-1, and they will be eager to rediscover the winning threat against their divisional rivals.The Broncos made the AFC Championship Game last season and found their spark on offence last week, beating the Cardinals 30-16 to move to 5-2 on the year, which makes this a key battle at the top of the AFC.GET UP TO £30 IN FREE BETS ON THE NFL WITH TALKSPORT BET*Denver Broncos v Kansas City Chiefs TipsKansas City Chiefs to winKenneth Walker over 0.5 rushing touchdownsJonah Coleman over 38.5 rushing yardsUnder 44.5 total pointsBet Builder pays out at 17/2Chiefs to prevail in AFC West battlePatrick Mahomes and the Chiefs do not quite have the offensive starpower of previous seasons but they remain a well-coached football team and a formidable unit on both sides of the ball.Kansas City are averaging 380.5 yards on offence, which puts them sixth-best in the NFL, and are allowing 323.3 yards per game on defence, which is the 14th-best record across the league.The Seahawks’ elite defence blunted Mahomes and his team last week, but Denver were unable to live with them in Week 1 and there are reasons to think that will be the case again in this rematch.The Broncos should have cornerback Patrick Surtain back, but defensive end Zach Allen, safety Talanoa Hufanga and wide receiver Jaylen Waddle could all miss out and their collective absence would be a big blow for Sean Payton’s men.The Chiefs, on the other hand, are far healthier and that could tilt this one in their favour.Walker can power into the end zoneKenneth Walker was kept quiet by his old team Seattle last week but the former Seahawk has made a big splash since joining the Chiefs in the off-season.Walker has rushed for six touchdowns on the ground – plus two as a receiver – including against the Broncos in the season opener.Denver’s Coleman looks mustardAnother running back, Denver’s Jonah Coleman, could also make a big splash on Sunday evening.Coleman was on the field for just three snaps and did not touch the ball in Week 1 of his rookie campaign, then he rushed for 39 yards from 10 carries against Jacksonville in Week 2 before being placed on the injured reserve list with a high ankle sprain. He made a promising return in last week’s win over Arizona, rushing for 54 yards from nine carries, prompting Sean Payton to say the Broncos have “gotta get him more touches”.The rookie running back is part of a committee backfield in Denver, but it appears his volume is only going to go up.Boost your bet with the UnderBoth teams look likely to lean on their ground attacks and that should keep the clock ticking over, which means that the Under is a big runner.Only two of the Broncos’ seven games this season have featured more than 41 points, while the same has been the case for two of the Chiefs’ six outings.The Total is set at 40.5 but Bet Builder punters are advised to take the 44.5-point line for extra insurance.GET UP TO £30 IN FREE BETS ON THE NFL WITH TALKSPORT BET*All odds correct at time of writingRemember to gamble responsiblyA responsible gambler is someone who:Establishes time and monetary limits before playingOnly gambles with money they can afford to loseNever chase their lossesDoesn’t gamble if they’re upset, angry or depressedGamcare – www.gamcare.org.ukGambleAware – www.gambleaware.orgFind our detailed guide on responsible gambling practices here.For help with a gambling problem, call the National Gambling Helpline on 0808 8020 133 or go to www.gamstop.co.uk to be excluded from all UK-regulated gambling websites.
