He's already had one season, this will be the 2nd. Like I said below, Trubisky is leaving after one year as a starter and is probably going pretty dang high. With a good season, the NFL would likely be interested sooner than later with his age. Why wait to get a guy with potential?
Anything is possible. Whether he wants to go early or not is a different story. Who knows. But the pros don't need to see extra whipped cream on top. It helps but this will be year 2 and that's often enough for those guys.
