ATL gives: 2nd round pick 48th overall for 2018 draft and a 4th round pick in the 2019 draft
SD gives: Casey Heyward 28 years old, 87 overall, SS dev, 89 speed, 92 man, 92 zone coverage
Contract: 1 year remaining on a 3 year deal - 5.71 million in salary, 2.49 million bonus (cap penalty)
For clarity, the picks that are involved came into the discussion because there was a trade war for Heyward between three teams - the Texans, Jets, and Falcons. It started originally as a 3rd and 4th from the Texans.
