I have zero objection to losing Kline, as far as I'm concerned the question here is whether Rowe is worth a fourth round pick. I assume we're throwing a first-round tender on Butler, but you can never have too many CBs, especially with Logan Ryan hitting FA after this season and presumably being a goner.
Rowe's measurables are very good, but falling to 5th or 6th on the Eagles CB depth chart is concerning. Hopefully that's just a matter of system fit with the new coaching staff, and he can thrive here.
