There appear to be 2 camps here so I don't think this is between you and I. I will respond to your post though. I do not see the depth you do. I'm looking for major league quality depth, this is supposed to be a contender. I do see the Twins trading for a major league starter, hopefully a top of the rotation arm, but that will be expensive. Then maybe a minor league signing bounce back candidate like De Leon, that would be your number 6. I would argue any starter that fits this mold is clearly behind Louie and this is why Louie is my number 6. You are not going to get anyone better than that to sign a minor league deal. That is exactly why a good team will have a quality young arm with options "wasting his bullets" in AAA.
Let's look at our depth behind the top 5 including that trade acquisition:
L. Varland has not had the injury issues of many of our starter candidates and is highly motivated to start. A bulldog. The fastball/cutter at 99-98 & 92-91 is lights out. Can he make it work at 96-95 & 90-89? If he is a #3 or better starter, forget about the pen. Duran is not starting because he couldn't hold up to a starter's work load, that's not Louie.
SWR has pitched in the majors, has the pedigree and is now entering the early part of his prime (still young), so even though his results have been spotty, he has a chance. Solid depth.
David Festa has the stuff to be a starter for a few innings, then he gasses out. The string bean needs to build up stamina and get stronger. He is not quite solid depth, more unproven depth. If he can't make it as a starter, he looks good in the pen to me.
That's it. After this you have to reach down to AA or below? Pierson Ohl, Andrew Morris, C J Culpeper, Corey Lewis, Zebby Matthews? Maybe one of these guys jumps up and makes a couple of good starts. Maybe.
Dobnak? Would be a fun story, but it's a fairytale.
Raya? Not yet anyway.
After that I would put Hendrick next for what's left at AAA, but after 2 good long relief outings the wheels fell off. Starter? Very iffy.
I'm sure I'm missing somebody and they will add, but the depth is not what it was last year. So far anyway.
