"He is just a little pocket rocket I reckon, he is just a little energy ball," Kelly said.
"He is almost like a pinball in the way he bounces off people as an energy ball.
That's what Brian Kelly thinks of his new five-eighth in Tanah Boyd.
And if you have ever been around Brian Kelly then you he isn't short on enthusiasm himself, so you know Boyd is definitely bringing the energy.
After coming back into the team due to an injury to Ash Taylor, Boyd has impressed and Kelly says he is enjoying playing with him.
"He is looking confident out there, so he has just got to keep it up," Kelly said.
"He is good to have around but sometimes I just have to tell him to chill out a bit if he gets too eager.
"Tanah is doing a great job and I am enjoying the combination ... we have just got to fix up our D (defence) now though.
Defence has been a focus for the Titans in recent weeks and something that Kelly echoed again today.
"The last couple of weeks just not being connected as a team, we have been feeling like we are defending by ourselves," Kelly said.
"We need to tighten up and go together rather than one out.
"There is a period in the game where you have all the momentum and then it will just flip and turn and it is up to those good teams that can handle those changes and at the moment we are not handling them the best so we have got to work on that."
Kelly and Boyd will get a further chance to strengthen their combination in attack and defence this weekend when they take on the 16th place Canterbury Bulldogs at Cbus Super Stadium.
The home ground advantage has been strong for the Titans in recent matches, winning four of their last five played on the Coast.
