I think you're overselling Big Mike's penchant for making plays. He played 121 career snaps at Wake and had 4 pressures and 7 tackles (PFF). Sometimes the light just doesn't come on for guys and I think that was the case with him. You know how Clawson always talks about wanting guys who football is important to and who *love* playing football? I think there was a disconnect there.
Btw, he's still in college; going to be a sixth-year DT at Western Kentucky this season.
McCollum ... there is an untold story there that I'm not going to share out of respect for the kid. It would explain why he looked great early but struggled to find footing as 2019 went on, and was lost in the shuffle in 2020 -- but I was told off record. I agree that he could've thrived in a different system -- though Wake's drop end position is basically an OLB/DE hybrid that rushes from a stand-up position.
Also recruiting rankings once you get past the top 400-500 prospects are for the birds.
