The Detroit Lions have been one of the NFL's most active teams in free agency, but even that doesn't mean that they are tapped out on spending. In fact, the total opposite is true. After a busy first wave of free agency, Detroit has managed to maintain its hold on a top 10 amount of cap space, and right now has a total of $25.8 million dollars left under the cap at this point in time.

Site Perched on the Gridiron produced an updated look at where things stand, and the Lions are still maintaining their hold on some money. Here's where things are at:

"1. Ind $65.8 mill. 2. Jets $43.8 mill. 3. Oak $38 mill. 4. HOU $37.6 mill. 5. MIA $33.2 mill. 6. Bills $29.2 mill. 7. CLE $28.2 mill. 8. AZ $25.9 mill. 9. DET $25.8 mill. 10. Titans $24.9 mill," the site tweeted.

Detroit's been able to manage their money well thanks to some creative deals, namely, the group of Trey Flowers, Justin Coleman, Jesse James and Danny Amendola not costing them too much money against the cap for 2019. That group right now only accounts for just north of $16 million this year.

A caveat? The Lions will have to dedicate about $7 or $8 million of that total to their draft class, so the real total could be under $20 million. Still, it's a decent chunk of change with which to work at this point in time. Detroit has filled most of their biggest needs, but do still have some to address. Right now, the team could use a linebacker, running back and perhaps a backup quarterback to add to the mix. If they could get that, they would be in an even better place heading into the 2019 draft in April.

The defensive line and defensive backfield have several stud players who figure to be around early in the draft, and those are two spots where the Lions could figure to need instant upgrades. Detroit also has needs at tight end, perhaps at wideout and also depth spots on the offense and defense. They also have plenty of draft picks with which to work. Now, they've got flexibility with those picks considering their fast free agency work.

Combined with a young linebacking group, there is a hope that the Lions could turn into one of the NFL's more elite groups on defense if they are able to continue the arrow trending upward. Certainly, there is reason for hope that could soon be the case, as they've already got a nice place to start with some solid and budding talents on the field. Getting a high draft pick into the mix will help this turnaround further.

Interestingly enough, many early mocks have had the Lions looking elsewhere than along the defensive front. Cornerback has also been alluded to as one of the team's bigger draft needs coming up, but that could have been dealt with enough to avoid an early selection. Detroit's next draft, whatever pick they might land, is still going to have to be heavy defensively and also at some of the offensive skill positions.

There's still a shot of adding some more players, and the Lions might just have a few more tricks up their sleeve. At the very least, they still have the funds to do so.
