Every year, teams strike it big with prized free agents who help them improve and become contenders.
However, there are also those teams that are left shaking their heads at the players they thought were going to be difference-makers.
With millions invested in each free agent, team officials must be certain of a player's ability before inking them to a long-term contract.
This year, there are players who fit the potential bust category. Let's take a look at a few of them.
Before Peyton Manning hit the market, Matt Flynn was the best available free-agent quarterback according to most.
However, Flynn has only attempted 132 passes in his NFL career, yet teams are willing to throw millions of dollars at him with the hopes he becomes the next great quarterback.
A prime example of why a team should be wary of Flynn is Kevin Kolb. The Arizona Cardinals traded a good corner in Dominique Rodgers-Cromartie and draft picks to Philadelphia in exchange for Kolb. They then signed him to a huge contract. A year later, the Cardinals are definitely regretting that decision.
Flynn could very well be the next great quarterback, but his limited experience shouldn't warrant the huge, multi-year contract.
Who Will Be a Bigger Bust?
A season after Peyton Hillis burst onto the scene in Cleveland, he fell out of the Browns' good graces, and his motives were questioned inside the locker room.
At running back, teams must be able to count on a player's toughness and willingness to work hard since their shelf life is generally limited.
With Hillis, questions remain with both after last season, and a team must be cautious in investing multiple years to a guy who could fizzle out after one.
John Abraham is getting old. Simply put.
His production was still good with the Falcons last season, as he recorded 9.5 sacks for Atlanta.
Yet a team that wants to sign Abraham will likely have to invest more than one season and a lot of money.
Abraham made $8 million for the Falcons a season ago, and with the 12-year vet entering the final years of his career, teams must think twice before investing multiple years in the aging Abraham.
A one- or two-year deal would be ideal, but anything over two would not be a smart investment.
