"Defensive coordinator Richard Smith is overseeing the Texans' switch to the 4-3 defense, which he thinks fits the team's personnel perfectly. " The above quote comes from the email newsletter from the Texans. I couldn't help but laugh out loud when I read it. So for 4 years now (up until a month ago) we have been doing our very best to assemble the best possible personnel for a 3-4 defense including switching out linebackers faster than some people change their socks. Yet after all that work and tinkering to get the perfect 3-4 defense, it turns out (according to Richard Smith) that we somehow managed to end up with personnel perfectly suited for a 4-3 instead. Isn't that special.
