SU hasn't offered Alwan because he is not 6'1 or 6'2 as he is reported online, he is 5'11. Coleman also isn't 6'2, he's 6'0.
Camden Catholic has a great staff in terms of getting their kids recruited. WVU offer doesn't surprise me as they offer a ton of kids in South Jersey due to connections to the region (current and past). However, I think he ends up at a UMass or 1-aa where he will be a good player. He's a little too heavy footed to play ACC football as a sawed off linebacker.
When I was still in the game, we used to say "if rutgers isn't recruiting a NJ kid, they know something." Their staff is very diligent with their in state scouting. Not to say they haven't missed their fair share but they know the NJ kids better than anyone else. Shakim Phillips a few years back is a perfect example. They didn't officially offer the kid until he already had 40 offers. It was all because he ran a 4.8 in their camp. No one but them knew this information. I only know because I know Shakim's coaches well.
