Christensen is roster insurance in the best sense: he can enter almost anywhere without forcing the offense to reinvent itself. Getting all the way back from the Achilles injury is what turns that versatility back into real value.
Strengths: All-five-position starts, versatility, system knowledge, initial-53 role, and veteran depth.
Weaknesses: Returning from torn Achilles and showed preseason rust; a full recovery is essential.
