In a 16 team keeper league, it has every position, offense and defense, except for offensive line. Been in it for over 10 years. The stats are skewed so that a good quarterback is worth 40-50% of the total weekly points. I've had Andrew Luck since his rookie year, last year, he was really bad, and then he was injured and out for the season. I popped Blake Bortles in, and he was excellent, I went 12-1, deep playoff run, filled Luck's shoes admirably.
I hate using 2 of my 3 offensive keepers on quarterbacks. Gut instinct says to keep Luck, up until last year he was one of the absolute best quarterbacks in my fantasy league. However, years of awful drafting by the Colts, a failure to develop or emphasize the offensive line, and a subpar scheme and limited skill position players, have left me doubting if he is the best move going forward. Bortles has a better scheme, young talent at the skill positions, and in my opinion, a far better offensive line.
I'm worried that Luck has hit a wall, which is exacerbated by a bad offensive line. The mistakes he makes are the same mistakes he has always made.
So, I'd like some guidance. Common sense, I feel, says Luck, but the bad decision at quarterback in this league can ruin you for years.
