It's one of these scenarios:
1. Canesport might as well be the National Inquirer with how they like to stir drama up. The article is behind a paywall, so I can't see context, but it wouldn't shock me if one of those tools asked a question along the lines of, "would not having a DC in place by NSD be a red flag as far as picking Miami?", just to coerce an answer.
2. He's being coached by his handlers to say things like this to create suspense.
3. He's trolling/has been trolling and is suddenly "getting cold feet" about potentially coming to Miami now that we're less than 10 days away from signing day.
Either way, if he truly wanted to be at Miami, it wouldn't matter. Didn't he just say a week ago that Mario wanted to play 4 down lineman and that suited his style better? Sounds like complete BS.
