"I'm going Tebow. That sounds crazy, but I'm going Tebow," Toomer said Saturday morning on ESPN New York 1050, as a co-host on "The Dave Rothenberg Show."
Toomer, responding to a question from Rothenberg, chose Tebow, in part, because of Sanchez's lack of "upside."
"[Tebow] and Sanchez are both not great quarterbacks," Toomer said. "The only reason why I'd say Tebow is because we've seen what Sanchez can do. This is his third year. Tebow hasn't even started for a whole season. Give the kid an opportunity to prove himself a little bit more and I think he can ... work on his technique."
Toomer later added: "I'm not a huge Tebow supporter, but when you're going against Sanchez, it's not that big of a curve."
Tebow, 24, completed nine of 20 passes for 104 yards and rushed for 68 yards on eight carries. Sanchez, 25, was 24-for-40 for 252 yards, but threw a brutal third-quarter interception that Andre' Goodman returned 26 yards for a game-tying touchdown.
Tebow led the Broncos on a 12-play, 95-yard touchdown drive in the final minutes of the game. The former Heisman Trophy winner accounted for 92 of Denver's 95 yards on the drive, including a 20-yard touchdown run on third-and-4 that sealed the win.
Pundits have questioned Tebow's NFL credentials because of an unorthodox throwing style. The left-hander had just two completions on eight attempts in a Nov. 13 win over Kansas City.
Toomer believes Tebow will "work tirelessly" to correct his mechanics.
"I'd rather have a guy with a deficiency like that, but at the end of the day he's going to put it all on the line and he's going to play with his heart," Toomer said. "I'd love that."
