i'm a Colts fan, and I've knew that the Colts signed DT Kellen Heard, so I want to know if he was a good DT back with the Rams

Colts are crippled with injuries on the defense, and they are thin at nose tackle, with only Antonio Johnson and Martin Tevaseu as the healthy at the position, but Antonio Johnson sucks and Tevaseu won't win the starting job right now.

So, I would like to know if Heard is a trustworthy defensive tackle. by his upside, he'll probably be the nose tckle, and i would like to know if he has the strenght, power, bull rush to become one.
