There is no unanimity, but the general consensus is threefold:
1. Someone like [Hunter] Pence would be great, though there are reservations about disrupting the current outfield.
2. Help for [Joel] Hanrahan would be huge. For some, a top priority.
3. Better do something. Some players are skeptical that anything more than minor moves will be made.
I continue to not understand the fascination many Pirates fans - and, apparently, also some Pirates' players - have with adding to the bullpen. The Pirates have the sixth-best bullpen ERA of any team in the majors, and they haven't gotten anything out of one of their top relievers, Evan Meek. It would be nice to have a more reliable lefty, but that's really the bullpen's only weakness. Joel Hanrahan has been a great closer, Jose Veras and Chris Resop have been very good setup men, and Dan McCutchen has been very capable as well. There also appears to be a good chance Chris Leroux can contribute for the rest of the year.
Hunter Pence would be a terrific addition, obviously, but the question is how much it would cost the Pirates to acquire him. They might also try a slugger such as Carlos Pena who might cost the Pirates less in terms of prospects.
