There has been a tremendous amount of “early hope” surrounding the 2009 San Francisco Giants, cloaking a somber reality.

As much as we all are hoping for a prolonged pennant-sniffing run for this like able bunch, we must be realists.

The blueprint exists for a dreadful 100-loss season.

I’m pulling for this team to hit, field, and pitch at the highest possible level and I have a lot invested in this team personally and professionally. That said, the possible shortcomings need to be recognized.

Here then are the Top 10 reasons the Giants will lose 100 games. Each of these items is worth 10 losses (plus/minus 2) and all are potential scenarios that we must be prepared to face as the summer unfolds.

1. TIM LINCECUM LETDOWN

It would be nice if the reigning Cy Young award winner could replicate last season’s success but that’s not likely. Even if he has a solid year, the threat of the Verducci Effect is real.

2. THE BIG MILESTONE

Randy Johnson is two bad starts in and still an eternity from the magic 300 win plateau. Hard to win when you get knocked around and they’ll trot him out all year in search of the hallowed milestone.

3. 126 MILLION REGRETS

Full disclosure here, I’m a fan of Barry Zito. A good guy and a philanthropist. He just can’t get outs consistently. Already “demoted” to the #4 slot you have to wonder what happens next if he keeps getting shelled?

4. EDGAR’S INTEREST

Off to a terrible start at the plate, he has shown defensive malaise as well. With a two-year deal intact, can’t see him over-exerting in August.

5. YOUNG GUNS GET SOME

As the season slips and slides down and down, the team will turn to the young stars to get some experience. Buster Posey and Madison Baumgarner lead the charge as wins no longer matter.

6. CATCHING A COLD

The best example of a Gamer is Benjie Molina but he’s the only catcher on the squad right now. He’s already getting nicked up and could be in for a long year.

7. STUFF BUT NO STUFF

Current fifth-starter Jonathon Sanchez has been a letdown. He’s got electric stuff but struggles to win.

8. DIMINISHING DEFENSE

Renteria is a big downgrade defensively at shortstop and Pablo Sandoval has a long way to go at third base. Eugenio Velez is atrocious off the bench and this turns close games into losses.

9. BETTER WEST

Even after just a handful of games, the NL West is looking far better than most experts thought. The Padres have already demonstrated that they’re at least competitive and Arizona and the Dodgers are superior.

10. POWER OUTAGE

In order to avoid protracted losing streaks, it helps to have the threat of the long ball. This Giants team will not have a 20-homer player nor will it hit 100 as a team. Yikes.
