I do have concerns about the current/rumored transfer class, but it's more because of what they have/haven't proven rather than their rankings.
There's a long way between high correlation and no correlation between transfer rankings and future team results. I'd say it's low enough not to be concerned about it. Last year, 247 had the following team transfer rankings. Alabama did well (their transfers had proven results, I might add), and Kansas might have done well without injuries, but the others weren't very exciting.
