Last month at the NFL Combine, Chip Kelly expressed interest in Bruce Ellington and the "interesting things" he brings to the table. Ellington is listed as a wide receiver, but also works as a returner, and occasionally in a running back role. Jim Tomsula and Geep Chryst seemed to have little interest in doing a whole lot with him. He got some opportunities his first year under Jim Harbaugh, but even then it was still limited to a certain degree.
Chip Kelly is sufficiently creative that opportunities could arise, and it opens the door for some intriguing opportunities with Ellington.
