Kristjan Sokoli is a nose tackle from Buffalo (Kahlil Mack's school) of Albanian descent. Currently, Sokoli has the 2nd highest SPARQ score of any player in Zach Whitman's database of 2015 players that were not invited to the Combine. In fact, Sokoli is a top 10 SPARQ player of any player in any position in this year's Draft (behind only Vic Beasley, Davis Tull, Chris Conley, Byron Jones and a WR/KR from Maine named Damarr Aultman).
Sokoli is 24 years old, is 6044 (six foot four and half inch), 290 lbs, with 34 inch arms and 10 3/8 inch hands. His wingspan is 79.5. He ran a 4.84 forty with a 7.19 cone drill, 31 bench press reps, and a 38 inch vertical. His Broad Jump was 9 foot 11 inches. (pSparq is 142.1, z-score (Standard deviation above the NFL average for his position is a whopping 2.2))
I have not spent time researching if Sokoli is a good player, but he is a late round type interior Defensive Lineman with high SPARQ numbers and length, the type of player I could see Seattle taking a shot at -- perhaps in Round 6.
