Colorado is one of the schools Walker is paying close to attention to, in addition to the Longhorns, Georgia Tech, Texas Tech, Texas A&M and Houston.
For some time now the standout athlete has not listed a leader, but has anything changed?
"I am pretty much completely wide open," he said. "I am still confused. It is hard distinguishing the differences between all of those schools."
One thing that gives the Horns an edge over the other schools is proximity to Walker's home. He has a brother who is a redshirt freshman safety at Purdue and the distance between Austin and West Lafayette, Ind. is something Todd is taking note of.
"At Texas my parents could go watch my games and that is the big thing right now," he said. "They can not go watch my brother like they want to."
A couple of other things Walker is looking at in his top choices are the type of offense they run and if he will have the opportunity to play quarterback. Some schools are recruiting him to play under center and others want to put him at another position, most notably receiver or defensive back.
However, quarterback is where his heart is and where he feels he can make a bigger impact.
"I have good speed and I make good decisions," said the 6-1, 170-pounder who has 4.4 speed. "I'm definitely a dual-threat back there but if I get in a good system I think I can make every throw perfect."
