Not "everyone" needs the Minor League.
I think Bruce will end up being a better player than Will Clark and he only had half a season of Minor League Ball before being inserted into the Opening Day lineup against Nolan Ryan, which I attended, in 1986. Clark jacked one of of Ryan that day and finished 5th in the NL MVP the next year, the year after that, and 2nd the year after that. Clark wasn't a 4-year College Player, either. He didn't use steroids and had a normal career with it's normal Bell Curve as injuries took their toll. He pretty much kept his OPS pretty level throughout his career.
It's possible that the way Bruce is progressing, that he may be ready to be the Opening Day Starter for the REDS in 2008.
Oh, and all of Clark's half a season was at High-A Fresno. He completely skipped AA and AAA.
He was 22 in 1986, and 21 when he was finishing College and playing for Fresno.
I believe in preventing players from moving up too soon so that their careers won't be ruined, but everyone is different and Bruce may be one that will thrive early in his career.
