While the talented Bowe, who was drafted by the Chiefs, didn't mind tooting his own horn, the more soft-spoken Davis let his play do his talking. Davis exited LSU with 141 receptions, seventh all-time on the school's list.
"He was more outspoken," Davis said of Bowe. "He said a lot and I was kind of the guy who would just try to leave it out there on the field.
"In a way it motivated me to do better. Not actually go out there and prove him wrong -- it's not all about that -- but I'm a competitor."
Davis will get every chance to compete for a starting job. With Parker out, the Chargers are searching for someone to line up opposite Vincent Jackson.
Davis' biggest challenge figures to come from Malcom Floyd, an inviting 6-5 target -- but he has trouble staying fit and on the field.
Kassim Osgood is another candidate, but he's more of a special teams demon.
That leaves Davis as among those expected to make a big push to be Parker's replacement.
"That's why they tell you to practice like a starter because you never know when you name is going to be called," quarterback Philip Rivers said.
The Chargers were ecstatic to call out the 6-1, 202 Davis' on draft day.
"I felt real fortunate that we were able to draft him," Lofton said.
