I guess there are only 3 players this year being:
Marcus Simms, WR, West Virginia
Simms is a 6-0, 200-pound, speedy receiver who put up solid numbers - 87 catches, 1,457 yards, 8 TDs - for the Mountaineers. He had entered the NCAA's transfer portal due to a alleged violation of West Virginia's conduct code but instead chose to try the NFL.
Charles Goldman of USA Today's Chiefs Wire suggested Kansas City could take a long look at Simms in the supplemental draft.
Shyhem Cullen, LB, Syracuse
Academic issues led to Cullen being declared ineligible for 2019 by the NCAA. According to Syracuse.com, Cullen "was recently measured at 39 inches in the vertical jump - a mark that would've tied for third among linebackers in the NFL Combine. He also checked in at 4.51 seconds in the 40-yard dash (t-fifth) and 118 inches in the broad jump (t-14th). He consistently pushes out 23 reps (t-10th) in the 225-pound bench press."
In three seasons with the Orange, Cullen recorded 43 total tackles, three tackles for loss and one sack.
Devonaire Clarington, TE, Northland Community College
Clarington is an interesting story. He was a big recruit for Texas back in 2015, but he ended up never playing for the Longhorns due to academic issues. The 6-6, 230-pound tight end transferred to Blynn Junior College and eventually Northland.
According to NFL reporter Dov Kleiman, Clarington recently ran a 4.6 40-yard dash.
I would look at the Cullen, LB or even Clarington, TE who ran a 4.6 sec 40-yard dash which is pretty damn fast for a 6'-6" 230 lb TE. He'll probably bulk up another 10 lbs - 15 lbs of muscle bulk and if he can hold his speed after adding extra bulk; he could be an imposing guy. jmho
