Somewhat interesting article on ESPN
ranking the position groups and where to find value.1 - WR
The ideal time to draft one for the best value: UCF's Javon Baker, USC's Brenden Rice and Washington's Jalen McMillan project as late-Round 2 or early-Round 3 picks. They could be potential steals there. All three have the potential to develop into No. 2 receivers early in their NFL careers.
Oregon State's Anthony Gould, Arizona's Jacob Cowling and USC's Tahj Washington are undersized slot receivers with Day 3 grades who could contribute early in multiple receiver sets.
2 - Offensive Tackle
The ideal time to draft one for the best value: Arizona's Jordan Morgan, BYU's Kingsley Suamataia and Houston's Patrick Paul all have second-round grades, but teams that need a tackle should be targeting one in Round 1. The talent and positional value are too great to risk waiting.
3. Quarterback
4. Cornerback
The ideal time to draft one for the best value: Iowa State's T.J. Tampa and Rutgers' Max Melton have second-round grades and you should be excited if your favorite team lands either one of them on Day 2.
5. Edge
The ideal time to draft one for the best value: If your team has more pressing needs but still needs to add a talented pass-rusher, there's some good value on Day 2. Western Michigan's Marshawn Kneeland, Penn State's Adisa Isaac and Colorado State's Mohamed Kamara are three names to remember.
Houston Christian's Jalyx Hunt, Mississippi's Cedric Johnson and UConn's Eric Watts are intriguing developmental prospects who should be available in in the middle rounds.
6. Defensive tackle
The ideal time to draft one for the best value: Florida State's Braden Fiske, Texas T'Vondre Sweat, Michigan's Kris Jenkins, Ohio State's Michael Hall Jr. and Oregon's Brandon Dorlus are excellent values in Round 2.
7. Tight end
8. Safety
The ideal time to draft one for the best value: Smith, USC's Calen Bullock, Maryland's Beau Brade and Miami's Kamren Kinchens all have third-round grades, making late on Day 2 a good spot to target a safety.
Oregon's Evan Williams is one of my favorite Day 3 prospects. He's versatile, flies around the field and plays faster than he ran at the combine (4.6-second 40-yard dash).
9. Linebacker
The ideal time to draft one for the best value: Trotter, Jacobs, Washington's Edefuan Ulofoshio, Ohio State's Tommy Eichenberg and Texas' Jaylan Ford are some of the prospects who could be on the board early on Day 3. Teams might not see that big of a gap between them and the next tier.
10. Center
The ideal time to draft one for the best value: If a team needs a starter, it should target one of the top three in the second round. Barton is the No. 32 player on my board, but he's not that far ahead of Powers-Johnson and Frazier, which means a team would really have to fall in love with him to take him in Round 1.
11. Running back
The ideal time to draft one for the best value: I really like Brooks and believe he's worth drafting late in Round 2, but teams should wait until Day 3 to draft others if they don't take Brooks. There are three backs with third-round grades and four backs with fourth-round grades after Brooks and Corum. The gap between those two tiers isn't great enough to justify taking one on Day 2.
12. Guard
The ideal time to draft one for the best value: Targeting an offensive lineman with the versatility to play guard and potentially another position early on Day 3 is sensible. NC State's Dylan McMahon would be a good value there if he's still on the board.
UCF's Tylan Grable tested well at the combine and is an interesting sleeper. All of his college starts were at left tackle, but he kicked inside to guard in certain situations and has been trained for a potential move to center.
