Before anyone can bring top-notch talent to Minnesota, they are going to have to win games. To win games, you obviously need talent and coaching; building a football program is much deeper than attracting just one or two top notch recruits like in say, basketball. (Even attracting those one or two players is difficult.)
Kill will win not because he somehow convinced a bunch of top talent to come to Minnesota and forsake other top programs. He will win if he identifies gaps within the way high school talent is evaluated, if he finds guys that fit his system who might be less heralded but fit his overall system more dynamically. (It will help if the top-level talent that comes up in the area stays in Minnesota, but still.) It has to be a gradual, incremental climb. Once the program can reach another level, it can try attract more high profile prospects and so forth. Think of how Mike Leach did it at Texas Tech.
Bennett's general theme of "He needs players ranked in the Rivals Top 250!!!!!1" kind of misses the forest through the trees. That's like answering the question of, "How can I stop being broke?" by replying, "Get more money."
