Yeah, and there's a 575 point difference between the three 2nd and 3rd round picks the Rams were able to trade, and the two picks the Texans have in those rounds this year. That's a cumulative 845 point difference which is more than the value of this years first round pick for the Texans.
In fact, if the Texans were to trade every pick they have in this draft, and the next two, they would fall around 325 points short of what the Titans got from the Rams, or a low 2nd round pick's difference (Don't know if Clowney's going to command that given the remaining injury concerns). This assumes that both the Rams and the Texans draft in the same position in both 2017 and 2018, and it also assumes one pick in each round for the Texans in 2017 and 2018 as opposed to the two 5th round picks they have this year.
