Ifs and buts will drive you nuts.
When you say "deep depth" you have to look at what the depth is. If I am among those trying out for one of the OF positions because I can hit a ball out of Camden Yards (BP speed) then that's not the deep depth you want. When you're working out Fernando Tatis and Arthur Rhodes you're looking more like you're grasping at straws for bodies rather than having deep depth.
You make the moves you need to make to improve the team. I give the chances of Brian Roberts coming back AND playing AND staying healthy AND reverting to 2009 form about 0.1%. Does filling it with the combos named really put us in the best position to win? No, and neither did it when Andino played there, nor were we filling the SS hole a few years back when we had about 8 guys play there during the year. That's NOT filling a hole, at least not on a winning team. Neither is playing guys out of position because you couldn't find anyone else and dealing with tons of errors.
You could always use pitching. Getting the ace allows you to push your current #1 starter to a #2, the #2 to a #3, etc. It makes the whole rotation better from top to bottom. If you get a #4 then you've improved 2 slots. That's why it frustrates me when this team tries to survive on a whole bunch of guys who would be 3-5 in other rotations. Stability in a pitching staff is crucial. For 15-18 years the same 4 guys (it would be 5 now) were ready to take the ball over 90% of the games year in and year out...and every year the Orioles won 90-100+ games. That was not a coincidence. Last year the starting staff was band aided together. Chen and Hammel on a good team are 2nd or 3rd starters. One year in the 70s I think the Orioles used a total of 5 different starters the entire year. Most of the time it was 6, maybe 7. The 2012 version went through 7 in 7 days. They were lucky last year the starting pitcher bandaids worked all year.
Roles in the bullpen are also crucial, you bring in the best guys to compete and win those spots, and run with them. The Orioles did this right last year.
Having the same names to pencil in game in and game out by your choice (not just because that's the scrap you had left over) is why you get a winning team. For years, they could write in Ripken and Murray plus several others. And before that, Brooks, Powell, and Belanger. You had a set leadoff hitter, set 3-4-5 guys. This year? You can pencil in Jones (all star), Markakis (very good) and Wieters (borderline all star). Machado has every look of being a very good to all star player. Everyone else? Davis at 1B is out of position, Hardy is a health issue, 2B is a dartboard, who's in LF which day, etc. There's no clear leadoff guy to set the table and there's no clear cleanup guy to build around. And every year as the Prince Fielders come and go and the Mark Teixeiras come and go, the Orioles don't have one. But we have enough AAAA players for 3 teams.
This team as constructed can't sit on its laurels from 2012 and expect to repeat it. It is not soundly built. It might be a nice looking beach house but might be built on stilts, with a good chance of crashing down.
