I feel the exact opposite. I love his calmness in the pocket. He's got swag, and his teammates seem to gravitate to him. Even in the one preseason game, he kept his composure--despite the OL playing poorly in front of him. That checkdown to A.J. Dillon and the pass to Sternberger being two examples. I also liked the way he easily threw "off platform".
My main concern with Love is not arm strength, accuracy, mental aptitude, leadership. It's the fact he has a bit of a windup, and I don't think he's the quickest getting the ball out. Hopefully, he can improve on that.
