That's hardly true. The Jags have more talent at receiver, running back*, offensive line, defensive line, linebacker, and the secondary. With the attention payed to special teams, I would hope the Texans would hold the edge there.
There was a player on the Texans that could mitigate many of these advantages the Jags have. But, we're all certain he won't be playing here any longer. The changes to the Jags have been both immediate and gradual. And, they're all positive. The changes with the Texans? It's a mixed bag. With the biggest change a big, fat negative.
* Forgot about Etienne, Robinson, and Carlos Hyde. Hyde's still better than anyone the Texans have. Cheaper, too.
