The Colorado Buffaloes program has turned around significantly since the arrival of Deion Sanders as coach two seasons ago. It has transformed from one of the worst programs in Division I college football to an attractive destination for recruits.However, it is not just the personnel that is changing, but also the facilities. The Buffaloes invested $1 million to upgrade Folsom Field and posted some photos and videos highlighting the transformation on X on Saturday.However, the reaction from fans was not entirely positive."That fake turf is going to tear up many ACLs," one fan wrote."People complain about field turf, but the field turf holds up and it’s green all year long and when it rains or snows, it doesn’t tear up," one fan commented."Now replace the big screen TV on North endzone, jenky sound system and put in LED lights," one fan wrote."Lol congratulations. You are the only school dumb enough to go from real grass to turf. Enjoy the knee injuries!" one fan added."The champs are decades behind," another user wrote.The Colorado Buffaloes began the stadium renovation in late MayIt was a quick renovation for the Colorado Buffaloes' stadium as they began in late May after the annual Bolder Boulder race. The first events scheduled to be held on the field are for the Fourth of July weekend.By switching from a real to artificial surface, the university is able to host more events, including concerts, during the football season. Athletic director Rick George spoke about the decision to switch to turf."I think putting turf down there gives us flexibility, certainly with the change in the College Football Playoff," George said. "Being a northern school, you don't grow grass after October, and having a game in December was a big part of that consideration. Plus, it gives us another field we can practice daily that will benefit our football program."While the new turf was expensive, costing $1 million, it is expected to last 10-15 years.
