No, the age factor is why they were available. The guys in their early 20's are either being protected, or they are HS draft picks that haven't advanced far out of the lower levels, which usually means they aren't worth being taken.
These are two of the most ML ready pitchers I've seen taken in a while, if you can pluck guys like this for free and they end up being a decent BP piece at a negligible salary you are winning. Even better if one turns out to be able to eat some SP innings.
Feels like they wanted these guys, not to be good, but to add depth to the options to eat innings....in lieu of giving some other end-of-the-market guy 2M.
If they are impact guys that would be unique because they can't make the 40 on another team.
