Looks like my previous Blog had a bad link. This one seems to be working for me.
I prefer the tier rankings over 1-100 type. Most tier 1's are in your top 100 type listings. Tier 2 prospects are usually 75-200 range. Keith Law pointed out that the difference between a #1 prospect and a #25 is usually huge. Where a 50th ranked player and a 100th ranked player is pretty small.
