Gallup has been received work in the slot during training camp, Rob Phillips of the Cowboys' official site reports. "Everybody's labeled me as just a deep ball threat, but I know I can do a whole lot more," Gallup said. "So me being able to come on the inside and run some routes from there, short, intermediate game, definitely can show that I'm more versatile than a lot of folks might think."

The Cowboys already have two capable options in the slot in CeeDee Lamb and Amari Cooper (ankle), so Gallup may not see a whole lot of action on the inside during the regular season. Nevertheless, anything that allows offensive coordinator Kellen Moore to get the best possible matchups for his elite trio of receivers can only help boost their numbers. Additional flexibility would also help improve Gallup's marketability as he heads into free agency next offseason.
