That was a pretty cool article. I just had time to skim it, but what jumped right out to me was this. There were more starts by UDFA's (14%) in the league, than 3rd rounders and only 2% less than 2nd rounders. I think that's a pretty astounding number, made more amazing by the fact that its been that way for the last 10 years.
Clearly UDFA's make up a significant number of starters. A number larger than all but the top 2 rounds in the draft. Obviously its a key element in roster development. Those teams that do it well, are the teams that DO well....like our Pats.
