Not sure but we left two spots for them.

I think we'll definitely sign another DT, but I hope its sooner rather than later.

Dan Klecko-Cut from Eagles, convertred from FB to DT. Only 5-11 275, not good fit for the Panthers needs, but Meeks does like em smaller.
Alphonso Boone-Cut from Chiefs, According to Jason la Confora (NFL network), Boone is the current top Free Agebt DT. 6-3 305, has pass rushing skills and is a good run stuffer.
Chartric Darby- cut from Lione. 6-0 302. Had 32 tackles last year. Remember him from the Bucs?
Shaun Smith-Cut from Lions. 6-2 325. In just 11 games last year he had 36 tackles & had 62 in '07.
Nic Clemens-Cut from Broncos. 6-6 300. Best attribute is size.
Jonas Seawright-Cut from Cowboys. 6-6 335. Not very atheletic, But very big dude, which is what the Panthers need the most at this point.
Langston Moore-Cut from Bengals. 6-1 305. Has some pass rushing ability along with run stuffing.
Jason Shirley-Cut from Bengals. 6-5 338. Not to sure about this guy, but from what I hear, he can clog the holes.
Rodney Leisle- cut from Cardinals. 6-3 315. Had a great preseason, with 8 tackles. Remember him from the Saints?
Marcus D. Thomas-Cut from Broncos. 6-3 305. 34 Tackles and 1 INT last year. Very athletic player & run suffer.
Steve Williams-Cut from Patriots. 6-2 300. Helluva lot smaller than Kemo, but he had 16 tackles and 2.5 sacks in the preseason!

These are just a few (the Better) of the DTs that have been cut. IMO, I think the Panthers should go after Shaun Smith. He would be a great addition to Carolina and would instantly make our Run D alot better.
