The thing is 'generational' RBs never make it to a contender because they usually get picked Top 5-7. Those Teams most of the time don't have a Q or a ultra bad roster, in neither of those situations a team is a super bowl hopeful by adding a RB.
If for whatever reason Robinson would slide to the mid 20s selecting him could turn the right team into an absolute favorite for the SB. Teams like the Chargers, Bills, Chiefs who have a terrific passing attack would become almost undefendable on Offense with a RB like Robinson. If the D spreads out to stop the passing attack Robinson would just destroy them against a light box. The Chargers have had Ekeler while he is a good RB he is not a downhill I'm gonna end you RB that forces teams to stack a box.
Top Tier Teams never get a generational RB in his prime, the 9ers tried this year with the CMC.
To me with how low of value a RB is in the NFL I would absolutely shy away from drafting one in the first round, unless I am one of the above mentioned teams. So for Truth I actually like the pick.
Having said that I'd completely hate it if EDC would draft him (hypothetically speaking as he will be far gone once we pick, I assume)
