Stewart spent his first two years in the league as a receiver that played quarterback occasionally.
"The benefit for me was I had the opportunity to get out there and run the sight adjustments, the hot routes and run against the one on one matchups and pretty much I needed to know where I needed the ball to be," Stewart said.
While the transition worked out for Stewart in the end the Bears hope Grossman has a more traditional patch to becoming a starter. The team plans on Grossman being the third quarterback with Chris Chandler backing up Stewart. If Grossman doesn't play as a rookie that will mean that Stewart is healthy and the team is making a run at the postseason.
Dick Jauron tried to initiate Cade McNown in his rookie season by playing him one series per game. The team will not implement a similar strategy with Grossman.
"Sitting down and watching is good, just to hear it for the most part," Stewart said. "It's like rapid fire. It may look good early on, but as the heat gets on your back it can really take its toll. And some guys are capable of handling it. It depends on the individual."
Grossman handled pressure at Florida and since being drafted 22nd overall by the Bears nothing seems to have changed.
"The speed of the game seems about the same as it was at Florida so far, but of course I haven't had a rush yet," Grossman said. "That could be harder."
