Until the Cincinnati Bengals fundamentally overhaul their scouting process or their personnel department, they can expect to keep failing on the vast majority of their draft picks.
To be fair to the Bengals and any other team, the NFL Draft is a crapshoot to begin with. However, it's even more so that way when you have the smallest scouting department in the league, which Cincinnati does.
Rather than taking fliers based on evaluations that can't be as comprehensive as the elite front offices based on resources alone, why not trade these future maybe-picks for definitely-good players now?
