Trade Analysis
The Exchange
On 1970-05-11, Detroit Lions received Len Persin, while Philadelphia Eagles received 1971 tenth round pick (#256-Tom Bailey (b)). Hindsight turns on what those assets actually produced for the acquiring clubs, not on the abstract value of a player name or draft slot.
Detroit Lions Return
Detroit acquired Len Persin, whose Lions tenure did not produce a comparable documented regular-season contribution. That result is the basis for Detroit Lions's C+ grade. Production created for another franchise is not credited back to Detroit Lions, and a pick later moved again is valued through the transaction Detroit Lions actually made with it. The goal is to isolate the football value that stayed with the acquiring team.
Philadelphia Eagles Return
Philadelphia used the 1971 tenth-round pick on Tom Bailey. Bailey remained with the Eagles for four seasons, appearing in 50 games and producing 186 rushing yards, 194 receiving yards and two total offensive touchdowns. That supports Philadelphia Eagles's C+ grade. A condition that never triggered, a player who never appeared, or a pick sent elsewhere is treated differently from a contributor who actually played for Philadelphia Eagles. The grade follows the realized outcome rather than the nominal size of the asset.
Value in Hindsight
The comparison is therefore specific to this exchange. Detroit Lions's result came from Len Persin; Philadelphia Eagles's came from 1971 tenth round pick (#256-Tom Bailey (b)). The chain stops when an asset leaves the club, unless the club received another identifiable asset in that downstream move. That prevents the evaluation from assigning a later player's career to the wrong franchise.
Final Verdict
The supported grades are Detroit Lions C+ and Philadelphia Eagles C+, producing Even Trade. The key evidence is concrete: Detroit acquired Len Persin, whose Lions tenure did not produce a comparable documented regular-season contribution. Philadelphia used the 1971 tenth-round pick on Tom Bailey. Those results explain the grades without relying on generic trade-value language.
