That's how I first got into the Sonics. The '79 champs, Gus Williams, Jack Sikma, Downtown Fred Brown, the uniform - it just clicked for me. It's a bonus that I happen to settle here in Seattle later on. The highlight was the Kemp-Payton-Karl years, culminating in the '96 Finals (against JPM's damn Bulls). That team had a former PBA import as their 6th man, Vince Askew (IMO he had the best post-PBA career of any import). But I don't know if I can still cheer for a Sonic team that's not in Seattle. I've connected the team to the city too much.
Back to topic, early PBA imports that I remember being drafted in the first round in the NBA:
Leon Wood (the Olympian, not the white one)
From this list, George Trapp was the highest at No. 5 from Long Beach State (same school as Glenn McDonald) in the early 70’s, followed by Otto Moore at No. 6 in the late 60’s and Freeman Williams at No. 8 in 1978 from Portland State (1978 is the same year that produced 1st-rounders McDonald, Hardy and Fil-Am Raymond Townsend, while a guy named Larry Bird was picked as No. 6). I found out later that were higher drafted imports who played in the 90's, Dennis Hopson, who came out as a No. 3 in 1987 and Chris Morris, a No. 4 in 1988.
