I mentioned this elsewhere, but I think they have an opportunity to get more information on the young guys if they use some rotation slots to pair them up in a piggyback scenario.
Let Ryan, Ober, and SWR do their thing. For the other two slots, pair up, say, Festa with Bradley and Matthews with Abel. Have them each go 4 innings. Maybe a 5th if the situation dictates. It's not like they'd be letting these guys go any more than that in a traditional setup anyway. Now you can gather information and build experience for four young starters instead of two. Could be a creative way to steal some development time. If Pablo returns, or there's injuries, you can reshuffle as necessary. Maybe Adams or Ohl can be a partner if an opening emerges or you think SWR belongs in this group. Maybe Festa kills it for a few turns and you give him a chance to be a big boy starter. You have a lot of ways to play this.
Doing this would shorten the bullpen by two members, but it would also save them collectively about 6-8 innings per time through the rotation that it would be required to cover. Given the emptiness of that bullpen cupboard, counting on fewer guys I think is a good thing.
I dunno. To me, this would be better than constant bullpen games with a bullpen you don't have
