All of this is true, but the system has changed radically since 2010-2011. We can no longer draft good players with signability issues with lower picks. The comp pick system has changed. The international bonus pool has tightened.
Look at 2010: We had 4 picks in the top 57, despite losing pick 29 and 80 for signing Lackey and Scutaro. Yes, we missed with Vitek & Brentz, but we got Robbie Ross for Ranaudo and still have Workman.
2011 saw us get 4 picks in the top 40, and we still have JBJ, Barnes & Swihart on the roster.
It will be hard to stockpile picks like that again while signing new free agents to replace those departing.
In 2012, we got 3 picks in the top 37.
In 2013, we got 2 in the top 33, including Kopech as a comp pick that was essential in bringing us Sale.
From 2014 to 2018, we've done no better than 2 in the top 51 picks. That avenue has dried up.
The IFA avenue is much harder now.
Our budget is maxed out for signing FAs.
We won't be getting a number 7 pick (like Beni) in the immediate future.
Our farm shows no sign of having high impact players available by 2019, 2020 or 2021.
I'm not saying it can't happen, but the context has changed sharply.
