Looking at the 2019 draft, there are some interesting possible trade partners, Green Bay (2 1st and a 2nd) is one unless they believe Kizer is the future. Certainly SD and the Giants are candidates as they have no QBOTF future on their roster and their QBs are getting long of tooth. Houston if Watson fails there could be one especially since they have the a 1st and 2 2nds. The Colts are also there with a 1st and 2 2nds. Not sure why they would trade up unless Luck gets hurt again. Atlanta is a darkhorse here. The Steelers are also a contender unless they believe in Rudolph. You also have to consider the Titans as Mariota is injury prone and hasn't lived up to expectations. NE certainly has the goods with a 1st and 2 2nds if they believe Brady is sliding downhill.
Since you have to take the gamble with Rosen for at least a year or two, I hope the team would seriously look to move what is probably going to be a high position and cash in on a later first and possibly 2 or 3 seconds to grab a T and G in the first two rounds unless a top flight WR is available. The 2019 FA list of WRs is fairly sparse. There are some good to decent choices out there for the Dline and LB in 2019.
