I have a tough time seeing Gibson as a top-40 prospect, let alone a top-25 prospect. He's projected to start in Salem again after putting up a .240/.321/.306 line with 24/33 SBs in the Carolina league last year. Since his very good 2009 in Lowell, he's put up two sub-.700 OPS seasons and had injury issues as well. He's still fairly toolsy (athletic, speedy) but strikes out way to much to sustain the well-below-average present power he projects to maintain. I just see a very low ceiling (future utility player) with a high bust potential given the high strikeouts and lack of strength. He's not especially age-advanced anymore (22 in high-A is slightly above the norm for serious RS prospects) so we can't give him a pass on that basis.

I think part of the discrepancy might be that SP.com is usually ahead of the curve on the sleeper-type prospects that take a bit of research to funnel out. Guys like H. Meneses or Stroup or T. Shaw won't put up especially gaudy stats and you really have to dig deep to get scouts to talk about them, so the national outlets are less likely to even consider them in the rankings and instead fall back on old prospect lists which had listed Gibson higher (he was in the top-20 after 2009 and early 2010, wasn't he?).
