I guess the fact someone is actually asking this question shows my age. Having said that, I was at that first bowl win and at every game during that era. Based on reputation Brad was absolutely the best hire we could have made. He came in with his high flying offense and made Tanneyhill look like a Heisman winner. We were setting offensive records. His downfall was Wally Burnham, a pathetic defensive coordinator. Won't ramble too much about all of this but the fact is Brad recruited his ass off at Carolina and his players were mostly responsible for our success and bowl wins under Holtz.
Personally I have very fond memories of Brad being here until close to the end. I truly believe if Wally hadn't been such an influence on Brad that he probably would have continued to have offensive success (look at his recruiting); couple that with a competent defensive coordinator and who knows where we would have gone.
It would be much easier to make the case that Brad Scott won with Sparky's players than to say that the roster Brad Scott left Lou Holtz with was responsible for Lou Holtz's success. Scott was left with a QB who had already been pretty successful in the SEC, two running backs that went to the NFL, and a pretty good receiving corps. Holtz first recruiting class had the Mr. Football recipients from 3 different states. Whatever talent was left from Brad Scott's tenure was developed by Holtz's coaching staff and it took a while. After Scott's team went 1-10, and Holtz followed with 0-11, it would be a stretch to say Holtz inherited a gold mine.
As far as recruiting is concerned, one of the best players Scott ever recruited, Marcus Robinson, barely saw the field. Robinson went on to play in the NFL and set the single season receiving record for the Chicago Bears which stood until 2012.
