Antonio Callaway promised NFL teams he's a changed man. The former Florida receiver had a series of off-field issues before he was suspended for the entire 2017 season following a credit care fraud scandal involving nine Florida players. "A couple players made some mistakes and chose to do something that wasn’t right," Callaway told reporters Friday at the NFL Combine in Indianapolis. "Obviously, it cost us our season. I moved on from it. I’ve grown. I’ve learned from the experience." The 5-11, 200-pound receiver took the field Saturday and put on a show at Lucas Oil Stadium. He posted the third-fastest time in the 40-yard dash at 4.41 seconds and was among the top performers in both the vertical leap and broad jump. That burst is easy to see on the field, especially when he burst on the scene as a freshman in 2015 with 35 receptions for 678 yards and four touchdowns. He also returned two punts for scores in his first year and added a kickoff return for a touchdown in his sophomore season, when he caught 54 passes for 721 yards and three touchdowns.
