WR Greg Childs is practicing after missing time with a calf strain during OTAs. “His size definitely shows up,” said coach Leslie Frazier. “He’s a big physical receiver which should (make) him a good target. He has good hands and runs very good routes. Still a little bit behind (in conditioning and schematically), but you can see the physical talent. Now it’s a matter of time whether can he get up to speed quick enough to help us early in the season.”
