Disagree. They drafted him and Stowers b/c they're installing a different kind of passing attack. He's, of course, not Puka Nacua, but it's that kind of versatility that intrigued them.
BTW, this should be obvious. All this stuff is just my opinion, and it's largely based on accounts from training camp, mainly from the Philadelphia Inquirer, and Jimmy Kempski, Kempski being my fave day-to-day guy out there.
Trading Brown was more of a financial decision than a football one. They couldn't pay everybody, they had some key contracts coming up, they won a SB with Brown, and got a pretty decent return.
Maybe they draft their WR 1 or WR 2 in next year's draft.
