Look at it this way, if you investing 20k per week. That's 280k for one, maybe two good players right? If you're a playoff team, getting a solid trainee in the second round is rare. So me, I save 280k and hope my "free" first rounder has some value. That's around 500k combined you have to spend on the exact player you want. No randomness, you can literally buy the skills you are looking for.
I bought Fennel and Law two seasons ago. Fennel was 800k and Law was 500k. I trained and sold Law midway through that season for 1.2 mil and Fennel is worth more than that now, he'll be 20 y.o. next season with an estimated salary of 12-15k.
Last season, after finishing last in DII, I was hoping for a great draft, I spent 300k on scouting and made back 294k after selling two draftees. Neither were what I wanted at all. The third was released immediately.
So you tell me, which strategy was more beneficial?
