Lattimore played with the 21-year-old at the Gamecocks for two seasons, and he believes that suggestions questioning Clowney's work ethic will prove to be wrong over time.
"He loves football," he told Sirius XM NFL Radio. "That guy loves football and that's why he's striving to be great.
"Once he gets around those veteran guys — say he gets around J.J. Watt, he's going to see all the success he's had, and all his practice habits, and what he has to do, he's going to feed on that and he's going to be fine."
Lattimore missed the 2013 season due to injury.
