About to be OTC: Mattison, Armstead, or Williams?

[Indy Blue]

About to be OTC with the final pick of my rookie draft for Team 1 below. Draft has gone as follows:

1.1: Josh Jacobs, RB, Oakland Raiders
1.2: Miles Sanders, RB, Philadelphia Eagles *Me
1.3: N'Keal Harry, WR, New England Patriots
1.4: David Montgomery, RB, Chicago Bears
1.5: Darrell Henderson, RB, Los Angeles Rams
1.6: Parris Campbell, WR, Indianapolis Colts
1.7: TJ Hockenson, TE, Detroit Lions
1.8: Kyler Murray, QB, Arizona Cardinals
1.9: Devin Singletary, RB, Buffalo Bills
1.10: Mecole Hardman, WR, Kansas City Chiefs
1.11 (Comp Pick): Andy Isabella, WR, Arizona Cardinals
2.1: AJ Brown, WR, Tennessee Titans *Me
2.2: Noah Fant, TE, Denver Broncos *Me

2.5: Deebo Samuel, WR, San Francisco 49ers

2.9: Irv Smith Jr., TE. Minnesota Vikings
2.10: Miles Boykin, WR, Baltimore Ravens
3.1: Jace Sternberger, TE, Green Bay Packers
3.2: Justice Hill, RB, Baltimore Ravens
3.3: Damien Harris, RB, New England Patriots
3.4: Darwin Thompson, RB, Kansas City Chiefs
3.5: Diontae Thompson, WR, Pittsburgh Steelers *Me
3.6:
3.7: Me

I think I want to take one of Armstead, Mattison, and Dexter Williams. I think all 3 are good running backs who could have a role if things break right. Plus I already have a lot of WRs/TEs and my RB's are a bit thin. Right now I think I'm leaning towards Mattison if he's still there, but wanted your thoughts. Which of those 3 do you prefer?

Would pick the best talent and I don't see it as rb in this position. You should be able to trade a high quality asset after the draft and get a better RB. If I had to pick one, would probably take Mattison.

Mattison or Armstead. I think both have a chance to play big minutes this year as both starters in front of them have injury concerns.

[Kkiddynamite]

Mattison for me

I like both but give me the 3rd rounder over the 5th rounder pretty easily (if cost is even)

I voted Mattison because I think he will have decent value, even as just Cook’s backup. A little more competition in Jax behind Fournette and less draft equity in Armstead.
