It doesn’t take long, does it?

The University of Hawaii starting quarterback du jour, David Graves, throws a couple of picks and his “it” factor becomes an “int” factor. People start ripping him on anti-social media and from the No Aloha Stadium stands. This despite two touchdown passes and one rushing before a rough patch on the back nine.

The man he replaced the previous week, Shane Austin, finished up ably for the woozy Graves and Hawaii secured a 35-23 win Saturday against Tulane — a must win for UH’s hopes of a winning season and Hawaii Bowl eligibility.

Maybe it’s hard to keep track of which quarterback you’re supposed to love with all your heart, forever and ever. If so, just remember it’s the one on the sideline, not the one in the game … the one who is in there actually running the offense of your favorite team, the one putting his health at risk on every play is the one you’re supposed to unfriend. Any little mistake, and you must yell at the TV that he sucks, or phone in to the radio shows and make a case for No. 2 to become No. 1 — again.

Then be ready to switch your allegiance again at the next change of starters.

Unless you’re an expert in mob psychology, don’t bother trying to figure it out.

IF THERE was one quarterback I thought was immune to the fickleness of the fans it was Nick Rolovich. He went out a winner 10 years ago, with eight touchdown passes against BYU (which, as a UH fan, you can and must hate with all your heart at all times).

Rolo’s Run at the end of 2001 is the stuff of UH legend — 20 touchdown passes in the last three games as the Warriors finished at 9-3. No bowl game, but he enhanced his legacy with an MVP performance at the Hula Bowl on Maui.

He was set to be loved forever by anyone claiming to be a UH football fan. There was just one thing he could do to change that: come back to UH as a coach — especially as an offensive coordinator.

The hero of 2001 is a subject of criticism in 2011.

Calling plays. It’s one of those things we all think we could do better than the guy who actually gets paid for it.

I think Rolovich is a very good coach.

I especially like the way he relates to his players.

I’ve questioned his play-calling once or twice, but overall I think it’s pretty good. That’s because a key element, in Hawaii’s offense as well as many others, is that the play that is sent in by the coaches is not always what ends up happening.

For UH, the quarterback and receivers read the defense even during the play and must adjust based on it. Also, the QB has multiple options. Once the play starts, he’s on his own.

The Warriors offense produced 482 yards and five TDs in Saturday’s win. Maybe it pales to Rolo’s Run at the end of 2001, but good enough to cut Rolovich the OC some slack, at least for now.

THIS IS BYU week. We can say that for the first time in 10 years for a home game.

Does it still mean something? Does it still resonate with the fans? Do those under 40 care at all?

We’ll find out Saturday.

Another question is how much this means to the Cougars. For at least one, the answer must be “a lot.”

Rolovich’s counterpart 10 years ago is also his opposite number this week: Brandon Doman, in 2001 aka, “The Doman-ator.”

The Cougars came in undefeated and complaining about being disrespected in the BCS formula — a sentiment UH used for motivation. Doman was considered a Heisman Trophy candidate, at least by a few people in Provo, Utah.

He might still be sore from Pisa Tinoisamoa’s body slam at the goal line at halftime of UH’s 72-45 crushing of the Cougars.

BYU is 8-3 and I’m guessing a touchdown favorite Saturday. But the Cougars committed seven turnovers when they were here last. If Doman isn’t better at calling plays than he was at making them at Aloha Stadium then, maybe Rolo can make another run.
