Collins is a JAG. Gregory is a bust. Taco is a bust. So, that nullifies your math. lol
Fact is that Marinelli has found 1 pro bowl DL in 7 drafts. Thats not good enough on any team.
drafting is based on the resources you put in it.
in the last 7 years
there has been 1 1st round, 3 2nd round, 2 3rd round with sprinkle of late round picks
taco is unknown who could be a big bust or not - this is his 3rd year going in
2nd round dlaw is star
2nd round hill is rookie tbd
2nd round gregory played in 1.5 seasons and will be in a cheap contract for 2 more years when he returns (see gordon for patriots)
3rd round crawford is an average starter
3rd round collin is a decent starter who is injured 25% to 40% of the time
they simply are doing significantly better than typical team.
these are the odds of drafting multi year starter (not pro bowl) based on all teams for more than 10 years
