Now I'm excited because this means he will indeed be a Cardinal. Was always concerned he could flip before arriving.
However, I'm not so sure how much he will actually play this season. We're talking about a kid who just turned 18 and should be in high school. Serious injury chances are why a lot of freshmen redshirt, especially with such a physical position like LB.
Now maybe he's an outlier and will perform like a seasoned veteran, but the odds are not so likely. I'm sure the coaches will be leary of playing him a lot, especially when there's several experienced and talented LB's on the roster.
It's usually a skill position true freshman who comes in ready to play, not a reclassified linebacker. But he wouldn't be doing this if he wasn't told he would get the chance of playing right away. So we will see.
