I wouldn't think that there would be any closers left in a 14 team league. I know they are all gone in my 10 team league. Just keep your eyes open for potential opportunities with set up guys filling in.
Every year getting closers is like playing musical chairs. There are a few that will stay all year long and play for winning teams. If you can land a couple closers on winning teams you can almost lock down SVs and possible help ERA and Whip in a 14 team league. I like to add several set up guys just to help with Whip and ERA and to get cheap wins every year. Maybe look into some of them.
