What are the average net yards that have 9 as the touchdowns, 145 as the attempts, and yards per attempt greater than 4.8?
SELECT AVG("Net yards") FROM table_35317 WHERE "Touchdowns" = '9' AND "Attempts" = '145' AND "Yards per attempt" > '4.8'
SELECT AVG("Net yards") FROM "table_35317" WHERE "Attempts" = '145' AND "Touchdowns" = '9' AND "Yards per attempt" > '4.8'
