Charlie Campbell of walterfootball.com has Brock Osweiler to KC in the 3rd.
"The Chiefs grab a quarterback to groom for a year or two behind Matt Cassel. Osweiler is visiting Kansas City before the draft.
Osweiler (6-6, 242) is big-armed pocket passer who has surprising mobility. The former basketball player has good athletic ability for being so tall. Looking at him, one would think he would be a statue in the pocket, but that is definitely not the case as he is a good scrambler.
As a junior this year, Osweiler completed 63 percent of his passes for 4,036 yards with 26 touchdowns and 13 interceptions. He also ran for 298 yards and three touchdowns. Osweiler set the school record for yards, completions and attempts. In 2010, he had only two starts, but played well, throwing for 797 yards and five touchdowns with zero interceptions, while also running for 168 yards and a score.
Osweiler has real arm strength and the gun to be a starting quarterback in the NFL. However, he is very raw and needs some work. If Osweiler goes to a good coaching staff that can develop him for a few years, he could turn into something. It wouldn't be surprising if Osweiler's stock rises during the lead up to the draft. He should have stayed in school and improved before going pro."
