Although, McGahee is expected to make a full recovery his chances of leaving school early for the draft are all but gone.
Still, a source close to McGahee said there is still a shot that McGahee might declare for the draft, but that would be a major risk considering his medical history.
McGahee had torn the ACL in the same knee during his senior season at Miami Central High School. His rehabilitation lasted seven months.
However, after that there are several players that will go in the first three rounds, but the order is yet to be determined.
Grossman will not be a first round pick and if the Bears decide to go in another direction in the first-round then he could be available in the following rounds.
In three college seasons, Grossman completed 677 of 1,110 passes for 9,164 yards, with 77 touchdown passes and 36 interceptions. A Bloomington, Ind., native, Grossman was the Heisman Trophy runner-up in 2001 and posted a 23-9 record as a starter.
This season, Grossman completed 287 of 503 passes for 3,402 yards, with 22 touchdown passes and 17 interceptions.
