Harrington wasn't a top-5 QB bust or anything like that, but he still wasn't any good. He was Captain Checkdown way before Trent Edwards or Matt Leinart. The Lions great pass blocking numbers at that time were misleading because Joey Blue Skies kept getting happy feet and dumping the ball off short. Case in point, his yards per attempt were as follows: 5.3, 5.2, 6.2, 6.1, 5.8, and 6.4. For being in a West Coast offense, his completion percentages were very poor as well (mid-50s on average). Maybe he would've fared better in a different organization, but I doubt it. I am surprised that he didn't spend his 30s as a backup at least though. He started at least 10 games every year of his career yet didn't play a game past 29.
