Hasselbeck played the past 10 seasons in Seattle after starting his career as a backup to Brett Favre in Green Bay and led the Seahawks to an NFC title and an appearance in Super Bowl XL, the only Super Bowl berth in the franchise's history.
There is no doubt that Jake Locker is the future for Tennessee, but there are questions about his readiness to play. Hasselbeck, though past his prime, is a quarterback who is capable to winning some games and easing the transition to Locker.
If it is Hasselbeck starting for the full year, the Titans could be in a good position. They have one of the best running backs in the league in Chris Johnson. They also have a talented, though concerning young receiver in Kenny Britt.
They still have some work to do if they want to make a serious run at the playoffs, but this move is about the future. Having Hasselbeck allows the Titans to play Locker when he is ready and not force him in too early and possibly damage his chances at success.
Overall, this was something the Titans needed to do, and this move should benefit them in the long run. We won't truly know the full impact of this deal until the jury is out on Jake Locker, but it will certainly be fun to watch.
