Agreed on the free agents, modest improvement. Pudge > Bard, Kennedy > Gonzalez, Marquis a big > Cabrera.

But more improvement is going to come from the bullpen overhaul, which along with the modestly improved rotation will avert the disastrous start like 2009. We can blow past your 10 game improvement just by not sucking like the start of last year. And I'm including a modest favorable Riggleman effect into that improvement. So the way I see it, those things along with the few free agents and bench depth, ought to make 15 -18 game improvement well within reach.
Can't disagree about about the bullpen, that is the basis of my optimism for improvement. I'm taking a wait and see attitude toward Riggleman, a losing record over less than half a season isn't enough for me to sing his praises.
Our starting pitching is going to be interesting early in the season until Wang and Detwiler get healthy. I think I saw you post about Strasburg making the opening day squad and I have been predicting that for a while. I am also concerned with our offense, despite improvement last season we were still below the median in most offensive stats and I don't see us getting much better. None of our outfielders are terrible but they aren't among the top players in the league either, we should have looked to upgrade.
I'll ask the same question about your prediction from last season. From posters forecasting a big jump I'd really like to gauge their level of optimism over the past couple years vs. the reality of 100+ losses. (I picked 73? in '08 and 69 in '09.)
