Pick #98 is not tradeable this year, it's a comp pick. If Broncos Swap first RD picks and add #63 and #94 that gives them enough to move up to #16. If Broncs swap 1st and add #63 that's enough to move to #19.
The Ravens traded up from #26 to draft Flacco. That's a lot closer to the end than the middle. The Texans had #18 which is only two ahead of where the jets are now.
I thought God'ell changed the rule that comp picks can be traded. For instance the Rams are sending the Janoris Jenkins 2017 rd comp pick to the Tacks as part of the Goff trade. If they dont get a 3rd rd comp pick for Jenkins the Rams will send their 3rd and the Tacks will send back a 7th as compensation.
