Sure it could, but why? Is there really anything wrong with the current system? The later rounds of a draft are certainly not garbage filler exclusively. Countless HOFers, All Stars, and contributing players happen throughout the draft. I don’t see anything wrong with the current system. I’m not sure teams are ever really drafting guys knowing they will just be filler...it’s just most end up just being that. Intriguing guys go off the board throughout the Top 20 or even Top 30 rounds. The last 10 rounds can seem somewhat useless with teams drafting guys as an honor (Elite HS guys already committed to go to college, coaches sons, etc.), but teams are certainly still drafting MLB guys in the 30s. To me 40 rounds is a solid number.
