From Allen American all area article:
"The Leopards’ record-setting offense drew plenty of attention during the 2020 season, but the team’s defense had plenty of say during the team’s 13-win voyage to the regional finals. That included a stacked linebacker corps with all-district first-teamer Slaughter tackling any opponent in sight. The 5-foot-10 senior averaged more than 10 tackles per game on his way to 142 for the year. He was also a valuable cog in Lovejoy’s pass rush with 10.5 sacks. "
Not sure what D3 or the transfer portal has do with whether he was offered a ship or not.
I doubt he was offered anymore than a pwo. However, he would have been an interesting player to watch.
Does not matter he is going elsewhere and McCasland has a lot of scholarships to award.
