How are the Vikings spending their money?

The Vikings were active before and immediately after the start of free agency, spending big bucks to re-sign defensive end Everson Griffen and quarterback Matt Cassel then bolstering their defense by adding defensive tackle Linval Joseph and cornerback Captain Munnerlyn.

Now, a month after the NFL's shopping spree began, all of the marquee free agents have been snatched up and the spending has died down around the league. But G.M. Rick Spielman and the Vikings have shown they still plan to tinker with the roster, evidenced by last week's signing of wide receiver Lestar Jean and their contract offer to free-agent safety Kurt Coleman.

As of this morning, the Vikings have just under $11 million in salary cap space remaining, according to overthecap.com, so they will likely carry financial flexibility into the 2014 season.

That space could also allow them to offer an extension to an emerging young player -- tight end Kyle Rudolph is an obvious candidate -- before that player comes close to reaching free agency.

That is a post for another day, though, because today, I wanted to take a closer look at how the Vikings have spent their money. The website overthecap.com is a valuable resource, and it allows you to look at how much money each of the 32 teams is spending for each position.

For example, even though the Vikings are still in need of a backup running back to take some of the burden from Adrian Peterson, something my colleague Mark Craig explored over the weekend, no team has committed more of their salary cap space to the running back position.

As of this morning, the Vikings had $61.28 million of their cap space allocated to offensive players and $52.93 million to defenders. Their three specialists combine for a $2.41 million cap figure.

Quarterback ($8.98 million, 20th in the NFL): The Vikings are spending $8.98 million at the quarterback position after bringing back Cassel with a two-year, $10.5 million deal. Christian Ponder, a former first-round pick turned clipboard-holder, has a cap hit of $3.23 million. A dozen teams are spending less at the position, including the Seattle Seahawks and the San Francisco 49ers, which shows how helpful it can be to have a quality starting quarterback on a rookie deal.

Running back ($19.16 million, most in the NFL): The Vikings have the NFL's best back in Peterson, but he also carries a premier contract. Peterson has a cap number of $14.4 million this season, the highest cap figure on the team and the highest among NFL running backs. And with $2.13 million on the cap, Jerome Felton is carries one of the highest figures among fullbacks.

Wide receiver ($12.29 million, 21st in the NFL): Greg Jennings, in the second year of his contract, will count for $7 million against the cap. But the rest of the team's wide receivers combine to make just over $5 million. At $1.64 million, Cordarrelle Patterson should be bargain.

Tight end ($1.97 million, 30th in the NFL): Only two teams are spending less money on tight ends than the Vikings. In the final year of his rookie deal, Rudolph has a cap hit of $1.47 million.

Offensive line ($23.05 million, 17th in the NFL): The Vikings have one of the NFL's better pairs of starting offensive tackles in Matt Kalil and Phil Loadholt, but they are only counting for a combined $11.14 million in salary cap space. Center John Sullivan has a cap hit of $4.75 million. The collective cap hits of those three will go up in 2015, but only about $3 million combined.

Defensive tackle ($11.27 million, 11th in the NFL): Joseph, the newcomer at nose tackle, has a cap figure of $5.75 million, fifth-highest on the Vikings roster. Sharrif Floyd, a 2013 first-round draft pick and the other projected starter at defensive tackle, carries a cap hit of $1.84 million.

Linebacker ($11.03 million, 24th in the NFL): The Vikings have a lot of youngsters at this position group, and those guys come relatively cheap. Veteran starter Chad Greenway, however, has a big cap number of $7.2 million, which ranks third on the Vikings behind Peterson and Griffen.

Cornerback ($9.81 million, 25th in the NFL): Munnerlyn was a significant signing for the Vikings, who needed a corner to play in the slot. But he carries a modest cap hit of just $3.33 million. Only one other Vikings cornerback, Xavier Rhodes, has a cap hit of more than $1 million. Derek Cox, a former starter in Jacksonville then San Diego, will make just $780,000.
