Agreed, and honestly, this isn't an arguable point. I've seen the numbers run and it's an incredible difference, all due to the size of the denominator. I am going to make up some numbers to prove this:
Let's say there are:
32 5*
350 4*
2000 3*
This is close to accurate on 247.
Total draft - 224 players (7 * 32)
If 20 5* get drafted, that's a 62% draft rate.
If 125 4* get drafted, that's a 35% draft rate.
If 79 3* get drafted, that' a 3% draft rate.
Interestingly, if 16 5* got drafted, 58 4* got drafted, and the rest of the draft was 3*, 150 players, the numbers would be:
50%, 16%, 7.5% - in this hypothetical, we have way more 3* than 5* and 4*, yet you have a much better chance to get drafted if you are a 5* or 4*, because the pool of those players is so much smaller.
This is simple math based on the larger numbers of 3* and 4*.
