By Rob Staton The supplemental draft takes place on July 15th and one of the prospects I've been asked about is BYU's running back Harvey Unga. My knowledge of him is limited - I had only one opportunity to watch BYU last year in the first week of the season. Jay Drew from the Salt Lake Tribune reports that the Seahawks were one of a number of teams keeping tabs on Unga in a recent work out. He was listed at 6'1" and 244lbs as the scouts looked on and would offer the Seahawks a size option at the position. He ran in the 4.64 range.
