Undated (AP) _ Some notable quotes last week from the world of sports: ---

''There was never any doubt in my mind it was going out when he hit it. This was the hardest lesson I've learned.'' - Rookie pitcher Roger McDowell of the New York Mets. McDowell, a sinkerball pitcher, hung a slider to Bob Brenly who hit a two-run homer to give the San Francisco Giants a 3-2 victory. ---

''No, I'm not a workaholic, I'm just slow. I'm committed to what I'm doing, but I'm not a workaholic.'' - Cleveland Browns Coach Marty Schottenheimer on his National Football League job that keeps him working about 18 hours a day. ---

''No matter what you do, there will be people who'll say, 'I told you so; they're not worthy.' I can't worry about that. The controversy is one of the best things that happened to BYU and to the WAC. We were in the paper almost every day. Suddenly people knew who we were, and whether they thought we deserved to be No. 1 or not, they realized we played some good football out here.'' - Brigham Young football Coach LaVell Edwards whose team has a 24-game winning streak, longest in the nation and finished last season with the national championship. ---

''I was misunderstood. I knew when I said it that something controversial could come out of it. There's a lot to be said for just going to college for four years. Take Bo Jackson. You think that going to Auburn for four years hasn't helped him, whether he gets his formal degree or not? Darn right it has. I'm not sure many of the critics understand that there are people out there in the streets, in the rural areas, in the ghettos, who'd give their right arms for a chance to compete and come to college for an education.'' - Auburn football Coach Pat Dye who told sportswriters that athletes don't need degrees to get something out of college. Dye was criticized for that statement by newspaper columnists and by university presidents. ---

''Our fans are great, I mean that. Our attendance is down but people forget how bad the economy is around here. When the national unemployment rate was around 10 percent, it was 20 to 25 percent around here.'' - Pirates Manager Chuck Tanner on Pittsburgh's low attendance which is the lowest in the National League with an average slightly above 10,000 per game.
