It's very interesting, the dynamic in play as we prepare for LeVeon Bell's return...I purposefully don't own him anywhere, and am not looking to acquire him, because, in my opinion, there are factors in play that could surpress his productivity, and maybe his availability, this year:
1. Bell himself: I'd love to hear the other side of the argument, but I'm firmly in the camp that Bell is a knucklehead of the first order. I think his knuckleheadedness runs so deep that it's inevitable that before too long, he finds a way to get in his own way again. Human nature scares me a lot more than the knee. Particularly, his own human nature: against the better judgement of the Steelers and his representation, he acted very stupidly in his absence, when he should have laid low, done his time, and even if it was only acting, portrayed an attitude of humble contrition. Instead, he's made himself a target before he's even stepped on the field.
2. The Steelers Organization: My opinion on Bell doesn't mean squat, but I'm an old man who has followed football passionately for a long time. I'm fairly certain that the Steelers Organization (over time) / Mike Tomlin (in the moment) concurs with my opinion of Bell, and they will take a defensive approach with him, conjecturing that he may likely engage in behavior that will impact his availability moving forward. The NFL plays into this as well. I think Bell will be very much on Goodell's radar, and subject to extreme scrutiny for the entire Season. Goodell is a 'Paladin' - he's very righteous about the Shield, and possesses a vindictive streak/righteous indignation regarding those who thumb their nose at him and the League, and Bell has acted quite stupidly in that regard.
3. The Steelers Organization is definitely in a 'window' right now, in relation to Big Ben's career arc. In my opinion, they are smart enough not to mess with something that's working, and are going to be very protective of their Super Bowl aspirations. DAW has been playing lights-out football in Bell's absence, both this year and last. This gives them the ability to be 'flexible' with Bell, meaning from a team chemistry/in-house disciplinary standpoint. His behavior messed with the Team (big no-no) and his replacement has played every bit as well in his absence, making it less important for them to just hand him back his old role on his return. The Steelers/Tomlin could certainly take an initial approach, under the guise of 'being concerned about the viability of the knee/easing him back in' - of rationing his playing time and forcing him to 'earn back' the carries share he enjoyed prior to behaving stupidly. DAW has, quite honestly, given them a perfectly legitimate excuse to manage his behavior and playing time from a defensive approach. They are certainly NOT an organization in crisis, 'just dying' for Bell The Savior to come riding in on his white horse to salvage a Season in turmoil...
In the NFL, talent almost always wins out, and Bell certainly has it, in droves, his return will warrant deserved playing time because having him on the field makes the Steelers better...but so does Williams, and I'm fairly certain that the Steelers have a locker room dynamic similar to what the Ravens had during the Ray Lewis era, and the Players themselves are going to be very protective of their window and team dynamic as they welcome him back. It's not like he was a victim - he engaged in stupid behavior that theoretically impacted a Super Bowl-run year. Strong team leaders know what to forgive and what to forget, and who and how to hold accountable. I dont' think Ben and others welcome him back with an 'all is forgiven' approach. More like 'great to have you back man, but we've got a good thing going on here. We've proved we can do it with, or without, you. You can make it better, but you'd better not make it worse'. Based on what I think I know about the NFL, the Steelers Organization and Tomlin, I drafted DAW in several High Stakes Entries when he fell to a reasonable slot (8th-9th Round), and I'm working every Owner in my trade Leagues already, trying to pre-emptively acquire DAW the minute Bell is reinstated...because early on, I don't think DAW's role diminishes that much, over time I still think he carries stand-alone value as a PPR RB2, and I think Bell is a ticking time bomb of 'I-don't-get-it-ness' that's one easy (IMHO) step away from being put on lockdown again by the League for a very long time.
Now, don't get me wrong - I feel Bell is going to be very productive if he stays clean...but I don't think DAW is going anywhere, and barring injury, even in an optimal situation I think it's going to be a time-share moving forward (albeit a very productive one) - enough to produce a low-end RB1 and a high-end RB2 in PPR.
...but I'd bet dollars to donuts that Bell will screw up again before this Season concludes. Just my opinion...
