Absolutely agree with you on LT. Anthony Belton has become my go to in that role although Charles Grant is a possibility too*. But I am very tempted by Hollin Pierce despite some reservations. Could he be our Trent Brown? And then there's Logan Brown who just, so perfectly, looks the part of a LT.
* My only concern with Grant is that he's 100% a zone scheme LT and perhaps lacks the power for a gap scheme.
As for Campbell and Ezeiruaku. Both excellent prospects. My only issues are that there are too many putting him in the first round now for me to include him in my mocks even if available too me. And Eze is excellent and I need to rewatch him, but how much better is he than Josaiah Stewart who seems to be there for the late second/third round? I'll need to look at them back to back to see. Eze's freaky arms are pretty cool though.
