CLEVELAND -- Splashy free-agent signings and high-profile trades did not fill the Tribe's transaction wire this offseason.

It was a quiet winter in which the Indians, coming off a 96-win season that saw them win the American League Central Division title and come one win away from the World Series, decided the depth they've accrued can carry them again into 2008.

"Part of what made us successful this past season was our depth, our ability to make adjustments, our alternatives and the strength of our farm system," general manager Mark Shapiro said. "When the White Sox, Twins and Tigers all had to go to their second tiers, our second tier was better than their second tier."

Remember that lesson when you look at the Indians' starting lineup and rotation. Baseball teams rarely end the season with the composition they opened it with, so an examination of the extras can prove just as pertinent as a study of the starters.

But the Indians had an additional line of thinking when they took the rare opportunity to bring back, essentially, the same team that walked off the field at Fenway Park after Game 7 of the AL Championship Series. They figure a season in which designated hitter Travis Hafner bounces back to his career norms can have more of an impact than any costly acquisition could.

The company line was that Hafner's '07 season was subpar only by his own gargantuan standards.

Clearly, though, his .224 average with runners in scoring position, his .167 average with the bases loaded, his drop in home runs (from 42 in '06 to 24 in '07), and his 54-point drop in on-base percentage (from .439 to .385) aren't going to cut it in the three-hole. The same goes for his woeful .148 (4-for-27) average in the ALCS.

Still, the man known as Pronk did manage to drive in 100 runs for the fourth straight year, so one can hardly call his season an outright flop.

"Last year was a disappointing year for me individually," Hafner said. "You want to play the way you think you're capable of. Last year, that didn't happen, so I feel like I have a lot to prove this year."

No one with the Indians seems to have a concrete explanation for what happened to Hafner. He wasn't injured, and he didn't slack in his pregame routine. If anything, he enhanced it.

"He had a human year," Shapiro said. "It was still a solid year for most big leaguers. I think his career and work ethic are a testament to the fact that he will bounce back."

To force the issue, Hafner began hitting in the indoor cages about six weeks earlier than usual this offseason.

If Pronk can return to his MVP-caliber form of years past, an Indians lineup that ranked sixth in the AL in runs scored last season suddenly looks substantially more imposing.

Cleveland Indians • Catchers: One-two punch behind plate • Corner IF: Time for Marte to step up • Middle IF: Extended look for Cabrera • Outfielders: Questions at the corners • Starters: Sabathia anchors solid staff • Bullpen: Eyeing a repeat performance • DH/Bench: Hafner seeking rebound

"If everything else happened like it happened last year, I'd take [Hafner's '07] numbers again," Shapiro said. "But at some point, someone else is going to pull back this year, and we're going to need someone else to take a step forward. I think Haf is one of the most likely candidates to have some improvement this year, based on his track record and how hard he works and how much he cares."

Beyond Hafner's performance from the DH slot, the Indians' bench includes some other areas for potential upside.

That begins in the outfield, where the initial setup of a David Dellucci/Jason Michaels platoon in left field and youngster Franklin Gutierrez in right could see some shuffling, if the statistics call for it.

Shin-Soo Choo, an intriguing prospect who had some big at-bats for the club at the end of '06 and is out of Minor League options, will join the Tribe sometime in May, once he's fully recovered from Tommy John reconstruction surgery performed on his left elbow. Choo will grab a spot on the bench and has the potential to work his way into the everyday lineup.

In the infield, the Indians are bracing themselves for the possibility that second baseman Asdrubal Cabrera, who electrified the club in the 45 games he played at the end of last season, will go through the type of adjustments that spoil many a player's second year.

Should Cabrera encounter some short-term bumps in the road, the Indians have brought in veteran utility man Jamey Carroll to lighten the load. Should Cabrera struggle for an extended period of time, a la Jhonny Peralta in '06, the Indians hope Josh Barfield will have righted himself at Triple-A Buffalo and be ready to contribute.

Another infield option is Andy Marte, who figures to be on the big-league bench, backing up Casey Blake at third. Marte, once dubbed the Tribe's third baseman of the future, is also out of options and needs to prove he can be a legitimate threat at the plate.

All of this talk of backup options might serve to sound as if the Indians are expecting the worst when it comes to their '08 club. Really, though, they are just being realistic. Injuries and inconsistencies happen in this game, and one can never comfortably predict where they will occur.

"I feel good about our ability to handle something unexpected in those areas," Shapiro said. "We've got a lot of depth on this Major League team. Last year, it was a separator for us from our competitors."

And if the Indians see Hafner morph into the Pronk of old, they'll have another separator up their sleeve.
