How does K9 perform at his best? You keep him from being ran into the ground by keeping his touches at a certain amount. It keeps him from getting injured and banged up, which is why Seattle used Charb, a lot as well, cause it kept K9 from also getting hurt.
Let’s say you pay K9, how much do you play K9 because now his contract dictates you gotta get your moneys worth for paying the guy. Do you still worry about K9 can possibly being ran into the ground? By playoff time, is K9, exhausted and beat up?
I think with Shaheed, if you don’t want or can’t justify paying a returner that much money, even though Shaheed will also play receiver and force safeties to continue to play high coverage, how do you replace an elite returner? Shaheed, can by himself, can the momentum of a lopsided game. That TNF game was looking rough until Shaheed took it back to the house. Seattle start out on offense in great spots because special teams with Shaheed puts Seattle in good positions.
Don’t think of it as only paying a returner big money, think of it as paying a player, cause he puts Darnold in better positions to succeed.
