Watch points

- Age curve. At 31, both level and resale value are on the downslope.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
Rated 16.6 overall — below regular-starter level. Defensively he reads as light defensive volume (0 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).
