interesting thread.
lets face it though, until the quality of players that come out of the draft improve, i dont think it matters what system you put in place, people still wont invest, because its not worth their time to spend all this scouting money to end up with a 7'1" PG with a $4k salary and atrocious SB + RB and all-star potential.
you can improve the scouting method all you want, but until the above situation improves, its still going to be a long slog and a risky financial investment to find great trainee's in your league's draft.
