Should be able to find good, young, exciting team from this list!

.You forgot Jesus Montero. Whether he catches when Mike Zunino gets here isn't really a huge deal - but he'll be in the lineup everyday.
I also see Kyle Seager as a 3rd baseman because both he and Ackley will play everyday.
I don't see Smoak getting too many more chances at 1B, given the fact that Liddi, Ackley, Montero, and Carp can all play there. (That is assuming Montero gets some reps over there once Zunino comes up).

If Seattle stays in house, I see this happening in 2014:

C - Montero, Zunino
INF - Seager, Ackley, Smoak, Franklin, Liddi, Catricala
OF - Thames, Wells, Carp, Robinson, Saunders
SP - Felix, Hultzen, Vargas, Paxton, Walker
RP - Capps, Pryor, Wilhelmsen, Furbush, Luetge, Beaven, Ramirez

That's 25 guys.

On the bubble:
- Francisco Martinez
- Franklin Gutierrez (if he can stay healthy - he should play in bubble wrap)
- John Jaso (not a bad guy to keep around if Montero switches positions)
- Chance Ruffin

IF THE MARINERS STAY IN HOUSE
2014- 2017

C- ZUNINO, MONTERO
IF- SMOAK, SEAGER, TAYLOR, LIDDI ,CATRICALA, ROMERO
OF- SAUNDERS, CHAVEZ, BLASH, J.JONES, CASTILLO

SP- HERNANDEZ, BEAVAN, HULTZEN, PAXTON, WALKER
RP- WILHELMSEN, CAPPS, PRYOR, LUETGE, FURBUSH, SNOW, LAFROMBOISE
