Jamal Adams is one of the best safeties in the league. He completes every task required from the safety position. He can play man coverage, deep middle, rob the center part of the field, blitz, defend the run, and even go above and beyond this, by doing absurd things like take on pulling guards, and stick to tight ends in the redzone.
As previously published here, and everywhere else, Adams is looking to be moved prior to the season, and the Texans are on his seven team trade list. Houston, in theory, has the safety position filled up.
