I don't think finding good players is easy. I do think some are more readily available from college to the pro level than others, like RB.
Every teams has decisions to make. There's only so much money to go around and more often than not, they have to let certain players go to keep more premium position players etc. I'm not a fan of premium contracts to RB's. Pass rushers, QB's, OT's and shut down DB's yes. the rest? mix and match get the best players you can for a contained cost.
i see Jones as a difference maker, but not at a position or body type I want to lock 10+ million per season in. Can easily see where he is allowed to walk.
Williams won't cost as much, and he's not as explosive, but he is a guy you can work an offense thru especially if they can get another pass catcher or 2. But what's his cost going to be?
I like Williams, probably more than a lot of you, but with the right pick you can certainly get a back like him too. The trade off between cap space and desired production is what Gute will have to decide on.
When you have a QB like Rodgers who is obviously in command of this offense, keep the horses in front to protect him and I think he can make a lot of things work. Of course you have to get the right guys, but it can be done.
