I hate the 2-gap system. It's boring and is not a good fit for college kids. It's the reason that only a school like Alabama, who gets the biggest and best, can run with consistent success. But if you look at those kids, how many actually end up being studs and get drafted high? None. The highest was Cody and he's done nothing. The rest of the guys were all LBs and DBs.
Kids in college don't have contracts, so they are not motivated with the fear of being cut and losing money. They are motivated by getting drafted (but only few have that opportunity) and because they love the game and have fun playing. You don't have fun in a 2-gap system. You can't attack. You have fun in football by beating your guy. Kids play defense to beat down the offense. You don't do that in 2-gap. You play paddy-cakes with the Oline and wait. Kids don't play like that in HS and aren't taught that so they struggle making that transition and take time. Even then, there's no reward.....hence no motivation. It's a thankless job. It also KILLS the pass rush. There's never any disruption to QBs on early downs b/c we only play run and there's no disruption in the backfield (unless we slant) so RBs have full vision to make cuts.....which is why we still struggle against the run. Our guys don't even run 2-gap correctly b/c they don't fire off the ball....they sit back and wait.
I would rather play games with the LBs and DBs, disguising or rolling coverages, blitzing, etc and leave the Dline to do what they do best....attack. If i was a player, i would much rather play for an aggressive, attacking, fun defense than a sit back and take it defense like we currently run. As a fan, i would prefer to watch that too. If you want to put butts in the seats, especially in a city like Miami, you have to win but you also have to be exciting! Plus, if i get beat with a couple big plays it seems better than allowing the offense to march up and down the field with 12-15 play drives that tires out the D and ruins it for the rest of the game.
