The Houston Texans are making moves to lock up their offensive line. Obviously, the big move recently was trading for left tackle Laremy Tunsil. Now, they've signed center Nick Martin to a three-year extension.

That's not money to sneeze at. Nick Martin got paid by the Houston Texans. Clearly, they're very serious about keeping quarterback Deshaun Watson protected.

Martin was a second round pick by the Texans back in 2016. Since then, he's appeared in 31 games – all starts.

Houston started the year 0-1 after a tough loss to the New Orleans Saints. However, they showed a lot of promise and clearly have a team that is trending upwards.

A big part of that is Deshaun Watson. The quarterback looked very good in Week 1, following a career-year in 2018. Obviously, the team's top priority should be giving him weapons and protecting him.

So far, they've done both of those things pretty well. DeAndre Hopkins is an elite receiver and leads a very strong pass catching group. Meanwhile, Carlos Hyde and Duke Johnson create a solid and underrated running back duo.

Now the offensive line is taking shape as well. With Martin and Tunsil as centerpieces, they're in a good position to keep Watson upright for years to come.

You have to wonder if this is the last move for Houston though. They've been very active over the last few weeks, clearly trying to make a push in the immediate future (as well as lock up the next few years). Could we see more extension to come? Or maybe some more trades? Or was the Nick Martin extension their final move for some time?

With the Houston Texans, you never know.
