No that's actually very fair. I think anecdotally, all of the spare parts guys they've brought in this year have had very obvious reasons why they could work out (Ben Heller throws 96 with movement, Pitching Bot wants to have Matt Festa's babies, etc.), while those guys from yesteryear felt more like projects. But that's anecdotal.
Less anecdotally I think the projections are more pleased with this bullpen too. Like last year, when Dan Szymborski ran his ZiPS article the Cubs bullpen was projected for 2.9 WAR. This was pre-Neris, so he'd bring it up to 3.4. Of that 3.4, 60% was attributed to Alzolay, Merryweather, and Neris. This year, before Thielbar and presumably with one more big-ish signing out there to be had, ZiPS has the bullpen at 3.6 WAR. Hodge/Miller/Morgan, the current projected top 3 relievers combined for 45% of that WAR. So I think the depth being better isn't just our fan-induced bias (though I don't want to celebrate too much no longer having a reliever projected for star-level production).
