Excerpt
"He's short (5 feet 11) and he suffered a handful of concussions in college.
Last summer, he was involved in a domestic incident with his girlfriend, eventually pleading no contest to disorderly conduct and performing community service.
Sims has tried to reassure Cardinals officials that it was an isolated incident, not a sign of more trouble to come.
The concussions are a worry, too, given the way Sims plays. He admittedly tries to knock out opponents, a style that has attracted attention from scouts. But it also makes them worry that he'll spend too much time on injured reserve because of it."
