Just FYI, Mahomes was not 'our guy'. He was not a target and was expected by the team to go earlier than our pick.
If you look at the history of this team and how they aggressively trade up for someone they've targeted pre-draft, this tells you they had no plans to draft Mahomes, unless he dropped in their laps. Which he didn't.
So all this woulda, coulda, shoulda that people love to propagate is just more of that hindsight criticism they seem compelled to dream up.
To be fair, the Saints were delighted enough teams reached for dreadful WR prospects to drop Lattimore down to us. Glad they did.
