The offer was tough to pass up.Jim Harbaugh, one of the most respected coaches in the game, was returning to his alma mater, Michigan, to resurrect the winningest program in college football history. So when Harbaugh called Vince Marrow to offer him a job, Marrow had to listen.Marrow, however, just couldn’t leave what he was helping to build at Kentucky. More importantly, he just couldn’t leave the people he was building with.”Michigan, being a Midwest guy and being from Ohio, it was very tempting,” Marrow said on Wednesday, “but it was just my relationship here with the administration and our staff and even the kids that I have coming in this year and the kids that I have recruited the last two years played a big part of that.”On Monday, Marrow signed a contract extension that will keep him at UK through the end of the 2018 season as tight ends coach and recruiting coordinator. The news ended a week of speculation about whether Marrow would stay or leave.”The last three days I couldn’t really go anywhere without people saying things to me,” Marrow said. “We were in church and the guy doing the offering said something, that is how deep it got. Relationships played a big part to just be honest with you guys.”Building relationships is the biggest reason why Marrow has developed a reputation as an ace recruiter, establishing a pipeline to Ohio and reeling in 14 prospects in UK’s 2013 and 2014 signing classes. As for the 2015 recruits who have already pledged to come to Kentucky, even they were a little surprised he told Michigan thanks but no thanks after sleepless nights last weekend.”I know that a lot of our recruits were very fired up because for some reason they just assumed I was gone,” Marrow said. “I told people that it wasn’t a slam dunk and a lot of people were saying that it was a slam dunk I was going.”Marrow, at the end of the day, had invested too much in Mark Stoops’ vision for the future of UK football to leave even for an opportunity like the one he passed up. And with an athletics department so willing to invest in Marrow, as well as in more than $150 million in ongoing facility upgrades, he sees that vision become reality.”It shows that our athletics director, Mitch (Barnhart), the route he is going, our administration and it shows were the program is going and I believe in that wholeheartedly,” Marrow said. “You look at the stadium renovations and just at the type of support that we have been getting over the last two years here. That always plays a big part in it.”His decision made, Marrow’s attention goes back to recruiting. He played a crucial role in securing classes ranked 17th and 29th by Rivals.com in the past two seasons, the two best classes in the history of the recruiting service. Marrow expects similar success come signing day in February.”We are going to finish strong just like we did the last two years,” Marrow said. “We have a couple more slots that we have to fill and it is just a situation where I know with me staying here a lot of those guys were very fired up to see that. We will see where we are going to finish, but I feel pretty good about it though. It is going to be pretty good.”
