You're severely underrating Ryan Rowland Smith.
And you keep harping on the thin bullpen. The bullpen was a strength of the club last year. Both Mark Lowe and Sean White pitched very effective set-up. Lowe in particular is regarded as a more than solid closer candidate himself.
They also went out and picked up another very good set-up pitcher from the Blue Jays in Brandon League.
This bullpen is not a weakness, and there's far more bridging to Aardsma than you credit.
The pitching may not be top 5, but it's certainly better than 19th in the league.
Perhaps you shouldn't be speaking so definitively about a club you apparently don't know much about.
