ST. JOSEPH, Mo. With Chiefs training camp now firmly underway, the teams second full practice produced several notable surprises and early standouts.Patrick Mahomes quickly reminded fans why hes one of the best quarterbacks in the league, despite coming off an ACL tear. The two-time MVP connected with speedster receiver Xavier Worthy early on for a beautiful touchdown pass in the back left corner of the end zone. Mahomes followed this up in scrimmages with a quick dropback and lob off his back foot to hit Worthy again for a touchdown.Kansas City is still looking to replace the production of Tyreek Hill, who was the last wide receiver to record over 1,000 receiving yards in a season doing so in 2021. Worthys speed mirrors Hill as the former set the NFL record in the 40-yard dash at 4.21 seconds.Another one of Mahomes weapons had a good day. Kenneth Walker III executed on run-after-catch opportunities on check-down passes and had a beautiful screen pass for a 30-yard gain.Its focusing on the details at practice; locking down exactly what we need to do, exactly what were trying to accomplish with each screen, Chiefs center Creed Humphrey said. Really just get the reps with the backs, the new backs and everybody just to get that cohesion.On the defensive side of the ball, coordinator Steve Spagnuolo inherits an inexperienced defense. Safety Chamarri Conner had a very impressive first two days of camp. Hes played a wide variety of positions as Spagnuolo continues his own unique methodology.He hasnt played as much nickel, hes played more safety, Spagnuolo said. But, thats really to get some of the other guys ready. I think we can always put him back there in a pinch, but this gives him a little more time deep that he didnt have last year. I think well still have some flexibility with him at both positions.Rookie receiver Cyrus Allen showed out in the first day of camp and continued that production. The fifth-round pick has quickly become a favorite target of Mahomes.I think Pats got some trust there, Head Coach Andy Reid said following Wednesdays full-team practice. Weve got a long way to go, but weve just got to keep growing.The Chiefs will continue training camp as players battle for roster spots and coaches evaluate both sides of the ball. While its still early, the first two days showed Kansas Citys core remains intact and several newcomers are already making their presence felt.
