Current Contract

Contract Value Index (CVI)

This Sione Vaki signing earns a B- CVI as a shrewd depth investment that reflects Detroit's commitment to building comprehensive roster depth. At $1.2M AAV over four years, the Lions are paying below-market rates for a depth piece running back, creating excellent value against the salary cap while securing long-term stability at the position. The minimal $0.5M guaranteed money in a $4.7M total deal shows smart risk management — Detroit can cut bait with minimal dead money if Vaki doesn't develop as expected, but the four-year term signals genuine belief in his upside potential. For a depth piece tier player, this contract structure is particularly astute given running backs' injury rates and the Lions' likely need for multiple contributors in their ground game. The deal gives Detroit a cost-controlled asset who could outperform his modest salary if he develops into a more significant contributor, while the low financial commitment ensures this won't become a roster albatross if he remains strictly a backup option.

Performance Analysis

Sione Vaki's F grade in Detroit is a tough early verdict for a versatile offensive weapon who was expected to provide a unique dimension. Vaki's ability to play both running back and receiver made him an intriguing draft prospect, but the NFL transition has been difficult. His F grade reflects limited production and an inability to carve out a defined role in Detroit's loaded offense. The Lions have so many weapons that finding touches for a developmental player has been challenging. Vaki's versatility should theoretically be an asset, but he hasn't excelled at any single role well enough to demand playing time. He needs a breakout moment to prove his skill set translates to the NFL.
