WESTFIELD, Ind. — Josh Downs didn’t feel threatened Thursday when he took the field with Keenan Allen. He felt invited. A receiver he once studied from afar is now his mentor after the Indianapolis Colts signed Allen to a one-year deal earlier this week.To some, mostly fantasy football enthusiasts, Allen’s arrival was viewed as a detriment to Downs, as the 2023 third-round pick enters the final year of his rookie deal. This was supposed to be the year Downs saw his target share increase exponentially thanks to the departures of AD Mitchell and Michael Pittman Jr., who were traded to the New York Jets and Pittsburgh Steelers, respectively. Downs had even hinted at that notion himself this summer.But could the acquisition of Allen shrink that opportunity or enhance it?“I feel like the more weapons you have, the better it can be (for me),” Downs told The Athletic after Thursday’s joint practice with the Atlanta Falcons. “However it’s supposed to work out is however it’s supposed to work out. Keenan coming here, we add a great vet to the room, a guy who can help in as many ways as possible. You just never know how things could go. … I’m excited for the future.”Colts sign Keenan AllenJames BoydDowns personally relayed that excitement to Allen on Wednesday, telling the six-time All-Pro, “I got a lot of my s— from you” just hours after Allen inked his new deal. They didn’t share the field much Thursday since Allen only took part in a handful of team drills. But the hope, Downs said, is that when Allen gets up to speed, they’ll become a nightmare tandem, particularly on third downs.And if Allen needed a reminder of what that could look like, Downs gave him a promising glimpse as he imposed his will in several one-on-one drills against Falcons defensive backs, followed by a key third-down catch in the final 11-on-11 drill.Each team’s offense started at its own 25-yard line and was tasked with leading its unit downfield for a game-winning field goal with just 1:05 left on the clock and one timeout. After Colts quarterback Daniel Jones started the drive with a short completion to Downs, Indy’s offense stalled following an incomplete pass and false start. Facing third-and-long, Downs got them back on track by winning his matchup and jetting downfield. The only reason he didn’t catch the pass was because Falcons cornerback A.J. Woods bumped him too early, resulting in a 40-yard defensive pass interference penalty that set up Spencer Shrader for a 48-yard field goal attempt.
