The Houston Texans' new head coach, Bill O'Brien, made a name for himself as the offensive play-caller for the New England Patriots from 2009 to 2011, during a time in which quarterback Tom Brady threw 103 touchdowns to only 29 interceptions.
In his final season under Bill Belichick as New England's offensive coordinator, the Patriots represented the AFC in the Super Bowl, and Brady threw for more than 5,000 yards for the first time in his illustrious career with 39 touchdowns and 12 picks.
While it's hard to peg the exact impact O'Brien had on Brady, a legendary signal-caller in the prime of his NFL playing days, one has to believe the former quarterbacks coach knows a few things about how to, well, coach quarterbacks.
Out wide, Manziel would have veteran stalwart Andre Johnson for at least the first few years of his career and the exciting DeAndre Hopkins, Houston's first-round pick in the 2013 draft.
On the line, Duane Brown is a former All-Pro left tackle, and Chris Myers—who'll be 33 in September 2014—is a top-flight center.
Then there's running back Arian Foster, the master of dicing through zone blocking.
He'll only be 28 in September, but the former undrafted-free-agent-turned-All-Pro has already logged more than 1,300 touches in his NFL career and played in only eight games this season.
Manziel would fit with the semi-rebuilding Texans, holders of the first pick in the 2014 draft.
