Bennie can gain wieght and get stronger, as long as he doesnt turn into linebacker size he will be fine. If your light like he is he can can put on muscle and maintain speed. I know for example two years ago i was about 165 and running a 4.8 my coach urged me to gain weight i did and got to 185 and have been timed running a 4.5 i gained alot of muscle and did more squats and continued running it helped me both ways.
