Height, Weight: 6-foot-5, 314 pounds
Rankings: CBSSports.com considered Gregory the No. 16 offensive tackle on the board and the No. 191 overall player on the board. Both CBSSports.com and NFL.com rated Green as a fifth- or sixth-round pick.
The skinny: Athletic, heady player with potential position versatility. His foot quickness and movement skill will appeal to zone-scheme teams but he must improve his strength and ability in pass protection to be considered a full time tackle. Could end up transitioning into a full-time center role. — Lance Zierlein, NFL.com.
