I think there's an extreme risk of Justin Jefferson being an extremely unhappy camper if he has no one better than Brissett to throw to him. Brissett doesn't have the best awareness, he tends to have 1-2 guys he hyperfocuses on, if Jefferson isn't one of them... well, Brissett is a good chemistry guy but he managed to rub TY Hilton the wrong way in Indy by getting more comfortable with the guys who were actually on the field, like Greg Doyle or Zach Pascal, than he was with Hilton. Hilton started missing games with injury and Brissett started ignoring him in favor of guys who were there the whole time. It's one of his more interesting flaws.
Frankly I'd rather avoid big name talent and go for some good second rank wideouts that aren't household names. Nothing is more overpriced than a household name.
But then having said that, I'd have never traded for Randy Moss and THAt was a fuggin home run so take this with the requisite sodium chaser.
