Building the roster

Two numbers on how he actually stocks a roster, from signing day to draft day.

1Roster ownership
2The NFL pipeline

Roster ownership

This coach's entire tenure (1979-1982) predates 2021, when transfer-portal tracking begins in this database. Portal usage cannot be measured for this tenure at all -- this is not the same as '0% portal'.

“His own” means the player arrived while he was head coach; “inherited” means a predecessor brought him in.

The NFL pipeline

at least4Drafted

players drafted into the NFL off his teams here (a floor — see the note below). None can be traced to who brought them in — there’s no roster record for these players here.

At least 4 — his 1979, 1980, 1981, 1982 seasons predate the modern 7-round draft, so this table’s pre-1994 pick counts are a floor, not a full count, for those seasons.

A pick counts toward his tenure when the player’s final college season was one he coached, a checkable rule rather than a claim about who developed the player. A blank note means the player is on a verified roster and arrived on his watch. “Estimated” means no roster record, so the final season is assumed to be the year before the draft.
