There are plenty of big names on the free agent market for 2012, but some of them offer more risk than reward.
As all NFL teams should have learned seeing the mistakes the Washington Redskins (with Donovan McNabb) and Minnesota Vikings (with Randy Moss) have made in the recent past, it's important to be careful who you invest in.
Here are five players that are not worth the money it would take to add them to the roster.
Steve Johnson has had a very rocky career so far with the Buffalo Bills. Overall, his play has been very good the last two years. He has recorded back-to-back 1,000 yard receiving seasons while hauling in 17 touchdowns in that time period.
However, those numbers don't completely make up for his antics. He cost the team big in the game against the New York Jets this season, and has had negative effects on the team multiple times in his career.
I'm not saying the Bills (or any other team) wouldn't be lucky to have Johnson's skills at their disposal. I'm just saying he is a risk and doesn't deserve the money he will certainly demand as a potential franchise receiver.
Kyle Orton has had bright spots in an otherwise mediocre career as an NFL quarterback. He played very well this season for the Denver Broncos in a win over the Cincinnati Bengals and for the Kansas City Chiefs in a victory over the Green Bay Packers.
And overall, his career statistics aren't terrible. 80 touchdowns to 57 interceptions with a career passer rating of 79.4.
However, he has never put together a solid season. And the improvement the Broncos saw when they replaced him with Tim Tebow certainly doesn't bode well. After eight seasons struggling in the NFL, Orton's place is as a backup.
The Miami Dolphins are likely moving on from Chad Henne, and thus the former Michigan Wolverine will be on the market. Several NFL teams may look at Henne, but any one of them would be unwise to invest much in him.
Since being taken in the second round of the 2008 NFL Draft, Henne has failed to live up to expectations. In his career he has 37 interceptions to just 31 touchdowns, with an accumulated passer rating of 75.7.
Henne has had time to develop into a good quarterback, and he just hasn't. He certainly has a place in the NFL as a backup, but he is not a dependable starter and thus no team should offer him a big contract.
In his career, Peyton Hillis has only had one good season. He had 1,177 yards and 11 touchdowns on the ground and 477 receiving yards with two touchdowns last year, and he parlayed that into a cover spot on Madden NFL '12.
However, in his other three seasons in the NFL combined, he has 984 rushing yards and nine touchdowns. And in those three years he only had one receiving touchdown.
It looks like 2010 was more of an exception than a sign of things to come for Hillis. He struggled mightily with the Cleveland Browns this season, and he has had injury problems throughout his career.
DeSean Jackson may be fast and elusive, but he's got terrible hands and he's a headache in the locker room.
Jackson undoubtedly has some value as a deep threat and a punt returner, but he's not a dependable every-down receiver. And his receiving yards, receiving touchdowns, and punt return average were all down this season from where they were in 2009 and 2010.
Acquiring Jackson's talent would not be worth the price a team would have to pay both in dealing with his off-the-field issues and giving him the money he believes he deserves.
