That's what the "cost control" people are missing. There's a reason why rookies are cost controlled. It's because half of them bust out of the league in 3 years, including top picks.
They look at guys like Nacua and Jefferson and assume we can get one of those guys at #28 ("Beane BETTER hit on those picks or else he NEEDS TO BE HELD ACCOUNTABLESDFGNSFGDKJNSFDKGNDFSDFKSFMSWFW#$%@#%$#%$#"). But when was the last time we hit on an offensive pick like that on year 1? Even Kincaid didn't have as strong a rookie year as those guys. It's not common.
Trade for a top young guy so we can still win the division this upcoming year, use next year's cap space for the contract, and draft a solid WR2/3 in late first or 2nd round for the future. That's the right move.
