The San Francisco 49ers were incredibly busy during the 2017 NFL draft, making six trades over the course of three days. The team ended up trading away nine picks, and getting back ten picks plus running back Kapri Bibbs. Of all the picks dealt, they gave up one 2018 pick (a fourth) and got two back (second, third).
We won’t know the full results of all these trades until next year, assuming they don’t turn one of those 2018 acquired picks into a 2019 pick. We can make some assumptions and predictions, but we don’t really know how those trades will work out for some time.
