Who is the most important addition to the Indianapolis Colts' defense this season? Maybe one of the rookies? Unfortunately, it won’t be Justin Walley now that he is out for the year, but J.T. Tuimoloau could be huge if he helps jumpstart the pass rush. And Hunter Wohler is looking like a versatile playmaker at the back end of the defense.
Or maybe it’s one of the free agents. Can Cam Bynum and Charvarius Ward revive the secondary? Maybe someone further down the depth chart can emerge. Lou Anarumo has praised backup linebacker Joe Bachie for his knowledge of Anarumo’s system, having played under Indy's new DC in Cincinnati the past several years.
