I think they are both ML pen pieces on another team, we just generally have one of the deepest pens in all of baseball.
I was looking at this earlier today. I figure that we have 12 pitchers in AA and AAA that should be ready to be bullpen pieces by 2016 or at least awfully close (Davies, Wright, Wilson, McFarland, Jones, Drake, Johnson, Kline, Bridwell, Berry, Givens and Escat). That's not counting Garcia who should probably also be on that list and it also excludes Gamboa who I think will never be successful.
I feel that keeping two of Davies, Wright and Wilson in the minors as starters as depth as well as Kline to see whether he develops is a good idea. I question whether Bridwell will be ready by then as he's the furthest away and I also think that keeping Givens and Berry in the minors as depth wouldn't be terrible. I also question whether McFarland, Jones and Escat are good enough. But realistically that means we need to graduate at least Johnson (or let him go elsewhere), Drake and one or two of the three guys listed above.
It would be awfully easy to have a bullpen made up of Britton, Brach, Davies, Drake, Johnson, McFarland and Wright next year.
