I was doing this in my head. Then I did some research. Curious where you stand. A more interesting topic is actually biggest bust of each round.
Undrafted free agent.....Adam Viniateiri
8th round....Troy Brown
7th ...Edelman
6th...the GOAT
5th...Ben Coats
4th....Aaron Hernandez.....just kidding. Bryan Stork?...Gostkowski? Asante?
3rd Curtis Martin
2nd Gronk
1rst John Hannah
Other notables.
At one point the draft was completely different. For example there were 34 rounds in 1962. Less teams and before the NFL merger I think.
Jim Nance....19th round
Craig James...7th round
Gerard Phelan was a 4th rounder, but I don't think he ever played
I think Marty Moore might have been the only Mr. Irrelevant
Nick Buoniconti HOF LB...13th round
