"Just excited to get him back in the building and going to work with him. Everyone knows how important he is to this offense," said Kelce on Friday.
Kelce and Hill enjoyed career-best seasons in 2018 as the main cogs of the league's No. 1 scoring offense.
The tight end led the team with 103 catches while recording over 1,300 yards. Meanwhile, the receiver caught 12 of Patrick Mahomes' 50 touchdown passes, nearly eclipsed the 1,500-yard mark, and he finished tied for the third-highest yards per catch average in the league (17.0).
Although the Chiefs appeared to draft an insurance policy for Hill in second-round pick Mecole Hardman - a lightning-fast deep threat who's also a punt returner - the club's offense likely still would've struggled to match last year's eye-popping production without its No. 1 wideout.
But with fears of a ban for Hill that could've derailed the Chiefs' season put to bed, the unit is primed to attack the NFL record books again.
