Since Sage got to Houston, he has thrown for approx 3300 yards. 24 tds, 23 INTs, lost 3 fumbles, rushed for about 90 yards, and scored 1 rushing TD, in 19 games.
Tavaris Jackson in the same period has thrown for 3400 yards, 20 TDs, 18 INTs, lost 4 fumbles, rushed for 480 yards and 4 rushing TDs in 25 games.
Yeah, Sage has put up slightly better numbers. About 20 more yard per game than T-Jack. Although, if Andre Johnson played for Minnesota, those numbers might change. Regardless, the Vikings need more help than 20 yards per game at the QB position. I love Sage and I hope he does well, but bringing him to Minnesota is as much of a gamble as leaving T-Jack as the starter.
