The schemes that the two play in are actually pretty different. In Frost's offense, the QB isn't that much of a weapon in a power run scheme. He's more of a facilitator.
In Taylor's freshman season, he had a 59.2% completion percentage and 1,631 passing yards. In his second season, 56.3% and 2089.
In Adrian's first year he had a 64.6% completion percentage and 2,617 passing yards.This season his completion percentage is currently at 59.1% with 1,711 yards and he's missed games, played slightly hurt, and the season isn't even over.
I'm not sure the two guys would necessarily do that great in each other's schemes is probably the point.
