Porter was the Colts' 5th-round pick in 1967. After 2+ seasons in Baltimore he was traded to the Eagles for a 3rd-round pick after playing 2 games in 1969.
Ron was installed as the right-side starter and started 9 of his 10 games for the Eagles in 1969. He started every game the following season, and 11 of his 12 games in 1971.
Porter moved to the left side in 1972, and started all 14 games in his final season with the Birds.
He was traded to the Vikings in September 1973.
Porter also played in the WFL with the Chicago Fire (1974) and Philadelphia Bell (1975).
(I assumed this was a 1969 pre-season photo, but Porter did not join the team until October.)
Note: I added Ron Goodwin to the Memorial Sidebar today.
