Assume, for the moment, that you could put find or assemble together a pro team in any major sport that really CARED about winning a game against the collegians.
That would be the hard part, afetr all. The main reason they stopped holding those exhibition games pitting NFL teams against college all-stars was that NFL players hated them. They regarded such games as a waste of time at best, and no one wanted to risk getting injured in a meaningless exhibition.
Could this year’s Ohio State Buckeyes beat the Cincinnati Bengals (assuming the Bengals’ starters were available, and actually wanted to win)? Not a chance. The Bengals would run roughshod over them. If they played 100 games, the Bengals would win 100 times.
Could the Arizona Wildcats beat the LA Clippers? Again, not a chance. The Clippers, if motivated, would annihilate the Wildcats 100 times out of 100.
Now, what about baseball? Well… here, a decent college team would probably beat a bad (or even a very good) major league team, every now and then. If a highly ranked college team like the Texas Longhorns played the KC Royals 100 times, I imagine the Longhorns could win 5 games.
I say that because every top-ranked college baseball team has an ace pitcher or two, one who’s not yet ready to be a regular starter in the big leagues, but who has the talent to make it there eventually. And in baseball, you can win a game with little more than good pitching.
Over the long haul, even the worst major league team would bury the best college baseball team. But in a few games, here and there, a top-notch college pitcher might have unhittable “stuff”, and shut down those big-league bats. If that happened, and the collegians manged to scratch out a few hits, they could win an occasional 1-0 or 2-1 game, even if they played against even the Angels, Braves or Yankees.
