I mentioned yesterday about how there are only 4 real sure bets left in the league, which may have been a bit short on guys like Drew Brees. That being said, there is another side to this coin, which includes some of the worst ways to spend your money if you are looking to make a few bucks. Here are my worst investments you can make.

Eddie Lacy

The Packers are really good, and they always will be. They draft well, they play the Vikings twice a year, and they seem to have the best QB in the game. When the QB is great, the RB takes a huge hit. Rodgers is that type of guy. All that being said, Lacy is not the guy I would be spending money on. Sure, Packer running backs have had success, but they always fall victim to the system that Green Bay runs. Lacy was a top fantasy pick this year, but hasnt really found a way to put it together. Will he be terrible? No, of course not. But he plays a position that many collectors are moving away from, and his production has suffered with Rodgers playing every game so far.

You can see where he is already a guy people are paying for:

Johnny Manziel

People are POURING money into Manziel, and though his prices have dropped because of lack of playing time, its still insane how much people will spend. Let me be perfectly clear that the jury hasnt even been brought to the courtroom on his skills thanks to Brian Hoyer playing well, but that is part of the reason he is such a bad way to spend your money if Cleveland is not your team. He could be great, but there is a greater chance he could also be terrible. Busts that are also famous tend to be twice the bust in the collecting world – as we have seen with guys like Tim Tebow. Collectors buy because they love the fame, and then they run for the hills when they dont perform. These types of players can just as easily be hobby pariahs.

Manziel is commanding nice prices still:

Cam Newton

After a record breaking rookie season, and a great year last year, Newton has struggled now in 2014. He hasnt exactly been bad, but he isnt living up to the standards he set in his first few years. Is this saying that Newton isnt going to be good? No, he can still be good, but if you are looking for a safe investment, this is not the rock you should look under. His prices are already high, and if you think that you should buy in, think again. If he succeeds, his prices wont get that much higher,  but if he falls on his face, they will plummet. Its too big a fluctuation year over year.

Here is where Newton sits with collectors right now:

Jimmy Graham and Rob Gronkowski

There is no doubt that both Graham and Gronk are some of the best TEs in the league. However, they are oft injured, beat up, and play a position that no one collects. I think that there is as good a chance that both could end up injured as much as the chance they both play well, and that does not spell good things for their cards. They both came in during one of the worst design years in recent memory, so their cards are not going to have that same cool allure that other rookies have had in recent years.

Robert Griffin III

Yeah, yeah, I know, obvious choice. Even so, this goes without saying that RGIII has demons surrounding his injury prone behavior and a team who has more ups and downs than a celebrity on drugs. There is just way too many variables that could play into whether or not RGIII is worthy of spending money on.

Austin Davis

Lets give credit where credit is due. Austin Davis has made the most of his season so far. So much that he will end up as a solid backup somewhere for the next few years. However, he WILL NOT be a starting QB, so collectors should not go and dump money into the one card he has on the market. That wont stop Panini and Topps from adding him to every late product this year, but it will all be for naught.

If you have your own, feel free to share, but these are my picks. A lot of moving pieces have to fall into place for these guys to stay or become successful.
