If I was forced to guess, I would say Ennis might be talking about JB (who knows), and Mali is talking about fans. I do agree, most likely talking about Brian though.
I think JBs point resonates to the extent that promises don't mean much at this point...you see teams go up there without a clue sometimes, still deciding at the last moment. Unless you're one of the first few picks, you aren't locking yourself in due to how things may play out with trades, etc. I wouldn't have an issue telling a kid we were going to pick him though - I'd tell a bunch. The more that are hanging out at my pick that my team is pretty high on drafting - the better it is for my job!
That being said, Mali seems to gone through the process the best he could, and his information says he should go...can't fault him for that. Hopefully it works out for him! Although I REALLY think he should have come back, and I don't think anything JB said this time was overly offensive...he could have cooled it a bit on Ennis, but he more or less right (assuming he was thinking he'd go top 10).
I also can't fathom his measurables are as high as they are though...I thought the kid was slightly more athletic than some, but he never seemed like a combine conqueror type. That confuses me a tad.
