Peace is the the single guy in the supplemental draft I like as a prospect. He is tall and appears to be fast and hrad to tackle based on tape. He seems to do a lot of sitting in coverage, mostly because most of his catches come against zone. This is partly due to bad quaterback play, though. He seems to have great hands and had to deal with a lot of off target passes.
Here is a pretty extensive look at his catches:
Dewayne Peace - Houston Cougars Football - WR - Receiving (via CollegeFBDude)
DeWayne Peace #9, Wide Receiver, University of Houston - Pro Scouting Highlights (via AESportsVideos)
