The arrival from Nottingham Forest is yet to make an assist or score for the Toon in the first month of the season.
But Howe said: "It’s harsh to say he’s got no goals or assists.
"Statistically, that is right. But you look at the chances he has created, and sometimes it’s not on him that players he has served haven’t scored.
"I always think that is a tough one. If Nick (Woltemade) scores Jacob Murphy's cross with the header, he gets the assist.
"Vice versa, if someone misses an opportunity, that assist doesn’t happen.
"He has done his job several times, but it hasn’t ended up in a goal. I have been really pleased with his general contribution and he’s looked a threat. You see what strengths he will bring.
"He has that raw pace and power that is so difficult to defend against. But I think he can get better and improve and we can help him do that as we continue to work with him."
