Simple logic says bouncing off of a wall, is more dangerous than playing where there is no wall.
How many twins went to the IL last year due to a wall???
I saw Tony Oliva rob a home run and bounce off of a HARD wall and act like nothing happened right infront of me, nowadays , it seems, too many do not have that durability.
Every thing in this thread is based on opinion and personal hopes, but the wall and injury, is also a reality.
