It's going to look like this for the AL West, IMO:
Starting rotation: Angels > Athletics > Mariners > Rangers
Bullpen: Athletics > Angels > Mariners > Rangers
Lineup: Rangers > Athletics > Angels > Mariners
Defense: Angels > Athletics > Rangers > Mariners
Bench/Backup players: Rangers > Athletics = Angels > Mariners
It seems like the NL West is actually going to be extremely competitive this year between these three teams. My theory:
Oakland A's end up 89-73, Angels are going to end up 87-75, Texas Rangers end up 79-83, Seattle Mariners end up 70-92.
Texas Rangers have the best lineup in the MLB, even without Bradley, because with a healthy Hank Blalock, Chris Davis as an everyday player, Josh Hamilton continue rocking, etc., they are still the best all around. They also have a very good bench when it comes to backup/utility players, and a lot of people underestimate how important these types of players are. This was one of the main reasons why Tampa Bay won the Eastern Division in 2008, it was because they had a powerful bench. The Rangers' defense isn't exactly horrible, because they do have some very good defenders like Michael Young, Taylor Teagarden, and Marlon Byrd, but they do have some very bad defenders to go along with that such as Jarrod Saltalamacchia. The part where they really fall off of is their pitching. They do not have more than 2 quality starting pitchers, and their bullpen isn't looking good. If they could possibly trade either Teagarden or Saltalamacchia to a team that needs a catcher (Red Sox!!!) for some pitching, either a bullpen arm or a starting rotation pitcher, they could get better. They could also benefit from signing a mid-level arm such as Odalis Perez or Randy Wolf, like the A's need. If they do these two things, and maybe one of their starting rotation arms becomes a surprise and has a monster season, the Rangers get in the Wild Card or win the division.
Oakland A's with a core group of Matt Holliday, Jason Giambi, and Jack Cust have a very good lineup, especially compared to last season. They have a very good bullpen, and very young, too. They also have 3 decent starting rotation pitchers, and have 2 very young, but questionable starting rotation pitchers (Gallagher, Outman) left. What the A's should do is sign a cheap, but not bad starting pitcher like Odalis Perez or Randy Wolf, and have either Outman or Gallagher take the #5 spot, whoever wins the spot in Spring Training. The A's have a decent bench, and decent defense. They have decent infield defense with Bobby Crosby and Eric Chavez, and average defense in the outfield. The Oakland A's biggest question mark going into this season is if Eric Chavez can stay healthy. They are my favorites to win the division.
The LA Angels of Anaheim are still a good team, despite not signing Teixeira or K-Rod. They still have one of the top 3 best starting rotations in the majors, and they have a very young and athletic team. Their lineup, anchored by Vladimir Guerrero, Torii Hunter, and Mike Napoli, isn't terrible, but not as quite as good as last year. I would say their lineup is above average, give or take a little. The Angels also have a huge hole at first base, since they traded their young first baseman, Casey Kotchman, to the Braves for Teixeira as what ended up being a rental. Their bullpen is still one of the better bullpens in the majors, even without K-Rod, as they still have Scot Shields, Darren Oliver, Jose Arredondo, and more. Their defense isn't terrible, their infield is going to be filled with young and athletics players, while their outfield is about average. In center, you have Torii Hunter, who is a legend for his amazing defense, but on either corner you have Vladimir Guerrero who has bad knees and you have Juan Rivera who is fairly slow. The Angels bench isn't bad because they have many options for each position.
The Seattle Mariners only hope is if half their team can rebound and be what they once were. If Carlos Silva, Kenji Johjima, Erik Bedard, Miguel Batista, and Aaron Heilman have good seasons, the Mariners might just be competitive. Their lineup is full of question marks, as they only have two real threats, Ichiro Suzuki and Adrian Beltre. Their bullpen has lost JJ Putz, and is full of question marks, just like their starting rotation. I think they actually benefited from the JJ Putz trade, as they did acquire a very good prospect in Franklin Gutierrez. I really don't think the Mariners are going to compete, but I think they are going to do better than last year. I think they should trade any of their older or more expensive players, such as Ichiro and Beltre for some serious prospects from a team in need, and start over. The Yankees would be a good option because they are looking for a center fielder, a position Ichiro can play. They could possibly get Melky Cabrera and maybe even Ian Kennedy or Phil Hughes. This would dump a huge contract off the Mariners payroll for the future. If the Mariners are truely looking to compete, what they need to do is the following: Sign a couple above average players to 1 to 2 year contracts, such as Jeff Kent, Rich Aurillia, and Ty Wigginon, and maybe even sign a arm for the rotation and bullpen, such as Jon Garland, Paul Byrd, etc. This should be enough for them to atleast have a chance to compete, but it really isn't worth it. If I was the Mariners, I would wait till Holliday leaves the A's, and for some of the prospects to develop.
