Battle to watch: **Amaro vs. Cunningham. Amaro is talented, and he can win matchups and catch passes downfield because of his athleticism. He proved it when he got a chance to play – three catches for 59 yards vs the Raiders – and he's shown it in practices. Can the former Jet hold up as a blocker? Well, he's still trying to prove he can. Cunningham (6-3, 250) is sturdier in the run game, and coaches like his physical style of play. The Titans will keep at least three tight ends, and Walker, Smith and Supernaw figure to be the three. Can Amaro or Cunningham prove to coaches and management they deserve to stick around as well?
