First, you don’t know who is or who isn’t starting. But Flores clearly believed he will be a starting caliber player.
Secondly, again, McKinney hasn’t been selected yet. So clearly not one team shares your high opinion of him or any of the other safeties. Every single team was content to wait til at least the 2nd round.
Same goes for Swift. Not one of the 32 teams have selected him. When he gets selected, that’s where he was supposed to go.
Third, you can’t guarantee anything. You don’t have the first damn clue. Because you didn’t even know that MIA would select him at 30, so how could you know whether another team (or more) might have done the same around the same time? You don’t.
However all these teams talk to each other. They send their personnel to the same events. They get a much better idea who might be interested in a player they are also interested in.
Clearly MIA valued Igbinoghene where they selected him and/or believed he wouldn’t be there much longer. They were willing to move down from 26, but no further.
That tells me something.
