If your athletes are such that you have to play a 10 yard cushion, then you have to play a ten yard cushion. I will agree with you that Brewster has been nothing short of a disaster at recruiting DB's. When theret (who is average), Collado (who is terrible in any role more significant that nickel back), and Carter (who is average at best, at least for now) are the the best three guys you have recruited in a 4 year period, you have got problems. I suppose you can count getting Royston to transfer as a recruiting victory. Even so, DB recruiting has been abysmal. The 4 starters are serviceable to terrible, and the team lacks depth.
But I will continue to say, they are playing the scheme that is best for their people, you can't just decide to be a press coverage team if you don't have the people. The biggest coachhing mistake in the scheme last week was not the scheme, but that they did not have the players prepared to impliment the scheme. The DBs were blowing coverages because they could not line up correctly.
