You're painting a very rosy picture. Campbell has been consistently labeled as lacking the arm length needed to play LT. Banks has been consistently viewed as having poor balance and athleticism as well as lacking awareness in pass protection. Banks is clearly listed as an OG by Dane Brugler and others.
Risky is gambling a high draft pick on a prospect that may need to be shifted to a new position and hoping he will perform well there.
We all know about Campbell's arm length.
In spite of that, several people have him Top 10 and many of those Top 5. So if the arms are an issue, the general consensus is he's a strong G or C candidate.
I am not advocating for using #10 on him, nor am I ripping my dick if the Bears do. But when I say not risky I mean, you take a swing for a T with a safety net of having him inside, vs some guys who simply don't live up to their draft status.
Draft a T at #10, and you take some degree of risk that he just doesn't end u being very good at all. But in Campbell's case, people seem to believe strongly his floor is a top IOL.
"Bansk has been consistently viewed as..."? Really? The views of Banks are anything but consistent. Some mock him in the 20's while others have him as the top tackle.
