Tiering all 32 teams (including the Texans) by offseason grades given by ESPN

The NFL offseason has hit its dry period as the Houston Texans, plus every other team, are taking a hiatus until training camp rolls around.

This is the time of the offseason when we get bigger think-pieces from outlets like ESPN to fill in the void and to kill time. One of those pieces was released by Seth Walder of ESPN, where he graded the offseason moves of all 32 teams in the NFL. Walder gave the Browns a less-than-ideal grade compared to other outlets but what did he think of the rest of the NFL?

In this piece, all 32 NFL teams are broken into grades given out by Walder, and yes, this goes by actual grade from A to D-. What grade did he give the Texans and what tier did they fall into?
