Let me start by saying I think Aaron Jones is being overrated. Yes he has upside, but he has also yet to play through an entire season. I think he has better than 50% to get injured in 2019. Especially if his workload increases. Honestly I think he is at his best around the 15 touch mark per game.
There are injury concerns with some other guys on the list. I think I would make this decision based on what kind of risk you want to take. In the last 7 years, only 11.9% of season RB1s came from a bottom 10 offense. What teams are highly likely to be there this year?

Now, there are some offenses projected to be top 10. Packers, Falcons and Colts among them. Which is unfortunate because all 3 of these have lead RBs with injury concerns. But I like Freeman the best out of them in terms of risk management. Most will likely agree with you that Jones is the best. I know Freeman is older, but he has also been the RB1 overall before. And we know his head is on straight. Just my opinion.
