COLUMBUS, OH – SEPTEMBER 19: Ohio State Buckeyes take the field prior to the game against the Northern Illinois Huskies at Ohio Stadium on September 19, 2015 in Columbus, Ohio. (Photo by Andrew Weber/Getty Images)Ohio State already has a top five recruiting class for 2019, as of now. The Buckeyes added a four-star commitment earlier today as well.One position Ohio State hasn’t locked down this cycle is quarterback. The Buckeyes have offered and targeted a bunch of high-level prospects, but have yet to pick up a commitment from one.Four-star Wisconsin commit Graham Mertz is one of the signal callers Ohio State is eyeing closely. The Buckeyes appear to have made some strides in their pursuit of Mertz, even as he remains committed to the Badgers.Eleven Warriors has the latest on the Mission (Kan.) Blue Valley North product.Things got a bit more interesting last month when Mertz stopped by Ohio State to scope things out a bit. Things are even more interesting now after something changed in the Gunnell recruitment, and some folks close to a completely unrelated Big Ten program – who seem to have some serious knowledge on the situation – insist that the four-star will end up somewhere other than Madison.Here is a look at Mertz’s 247Sports Crystal Ball. Ohio State and Minnesota (presumably the unrelated program 11W was referring to) are tied for the lead in predictions.Notre Dame is also lurking for Mertz. The Fighting Irish have not picked up a QB in this class yet either.It will be interesting to track Mertz’s recruitment over the next few months.
