first impression is that you will do well in the power categories and have a surplus of closers as you are deep there.
looks like posednick is your only sb threat. you may consider trading a closer for another speed guy to plug in at utility or wherever.
your starting pitching looks pretty good if a few pitchers live up to expectations - contereras, escobar, garland for example. may want to keep an eye on your starters and consider getting a top tier starter to anchor your staff. on the other hand you may be able to get by with the starters you have.
overall, very good looking team, and if your league values closers as highly as mine, you can trade one away to improve on other areas- sb's or starting pitching.
