Ok forget Barkley then. Would the Chiefs had lost the Super Bowl if they traded for Leveon Bell?
This is a better scenario. Now, in this scenario, how do you design the Offense? What do I mean by this? Well, what does KC do? Answer to that, they don't run a balanced attack and they don't use the rushing game as a focal point of their offense. They use Mahomes to throw the ball all over the field. So, the question you have to ask is, does KC really need a back such as a Bell or Barkley? If you look at Bell, BTW, his numbers have tanked, but lets say they did bring him in in 2018, then does it benefit the Chiefs to take away 150/200 throws from Mahomes to give to Bell in order to run the type of Offensive scheme that fits him? More importantly, does Andy Reid ever do that? I don't think so. If you do sign Bell, how do you get that done? You don't have the picks because you used them to bring in Clark. So you want to then trade Clark for Bell? Well, I doubt the Steelers would do that but lets say they do, then how do you make up for him on Defense and what do you do about the cap implications that bringing in Bell means? I man, as we all know, Bell didn't play in 2018. He sat out and that's because he wouldn't play for the Tag amount so what would he have cost and how does KC manage that cost and what does it cost them to do that?
See, you can't just say "Oh, if they had signed player XYZ, then they are champs" cause there are moving parts and it doesn't work that way. For every action, there is a reaction and you can't know how those change the dynamics. It's a butterfly effect thing.
