Wade Smith with the Miami Dolphins back in 2004.
You might remember Wade Smith from his time in Miami from 2003-05, where he was one of the few decent draft picks from the Dave Wannstedt and Rick Spielman-era that began this slow death of football in South Florida.
Smith is still in the league, and he has appeared to have aged like a fine wine, as in his last four seasons with the Houston Texans, he has gone to his first Pro Bowl and been a key part of a successful offensive line in Houston.
The Dolphins just recently hired former Texans offensive line coach John Benton as their new assistant offensive line coach, per Omar Kelly of the The Sun Sentinel, (I wondered why they didn't just give him the job outright but alas, Jim Turner will apparently never leave us), and considering that Smith has had his best years with the Texans under Benton, this signing would make a lot of sense.
This isn't a signing you're making for the future (Smith will be 33 on Week 1) but rather a stopgap until the younger players along the offensive line develop more.
But Smith would make an excellent stopgap at guard, made better by the fact that he will be working with an assistant he trusts, while also providing some much-needed locker room leadership.
