There's a lot of funny business that goes on behind the scenes. If an SEC athlete has bad grades (huge speculation here) with all of the bending-over-backwards they do for them, it's a huge red flag.

And grad school is even more demanding than undergrad. You not only have to get decent grades. You also are expected to contribute to either research or teaching students, or both. If anything, the standards should be higher for grad transfers, especially when you consider how limited the spots are at BYU for grad students compared to undergrads.
