Let me make the pro-Hawaii case and the anti-Fresno State Case.
There's a very distinct strategy that, given the right luck, you can with with at Hawaii. Basically, you recruit an international team with some Hawaiian players. You take the best 2 or 3 players on the island, if they're good enough, for free. The rest of your big 6 money is used to scout and recruit internationals. Let's say you have 4 openings and 25k of PAC-10 post-season money. If you're at C prestige, you scout Hawaii and take the best 2 players on the island for 5k total, assuming they're good but not amazing players that others don't want to come after. Now, you have 80k to go scout and recruit international guys. There are plenty of gems hidden among the 1-star and no-star internationals. With 80k to go find 1 or 2 internationals, you're bound to stumble upon some top guys. Once you make a few PITs, maybe a NT or two, your prestige starts to get into the range where your PAC-10 mates can't challenge you for the good recruits on the island anymore without putting the rest of their class in danger. You can start pulling in any elite recruits on the island for fairly cheap and still have a similar budget to go after those international gems. Obviously not an ideal situation, but it can be done.
Now Fresno State, on the other hand, I think is marginally more challenging. While you are in the PAC-10, you have the lowest baseline of any Big 6 school at B-. Any recruit to your north will also be within 200 miles of both Stanford and Cal (including recruits who are in Fresno!). Any recruits to your south will be within 200 miles of UCLA and USC. Basically, you're always going to be battling for recruits with 4 schools, 2 to the north and 2 two the south, that have a decent-sized to large baseline advantage on you. It's possible to put together a few decent teams, but putting together a strong Fresno State program is the most difficult place to do it in the Big 6.
