In yet another under-the-radar agreement that won't be the lead story on SportsCenter, N.D. Kalu re-signed with Houston for one more year.  Kalu isn't going to be pushing anyone to start at defensive end, but he's a valuable rotation player who provides a burst off the bench.  Much like Ephraim Salaam, his return keeps some much needed depth and leadership around.  Well done, Rick Smith.
