Generate text that refutes this claim: Collisions heighten antagonisms.  When someone gets hurt in a collision at the plate, the injured player’s teammates are more likely to hold a grudge—and to try to get even. There are numerous opportunities to do that, whether by aiming a pitch at that player, or by seeking another opportunity to hurt him. When Posey was injured, the Giants’ General Manager Brian Sabean said, “If I never hear from Cousins [who hit Posey] again or if he never plays another game in the big leagues, I think we’ll all be happy.... We’ll have a long memory.” [1] This is exactly the unsportsmanlike behaviour engendered by these dangerous and unnecessary plays.  Former MLB catcher Mike Matheny noted that catchers don’t forget when they get hit, saying, “I think you just put a mark in the column that that kid took a run at a catcher. To me as a catcher I know the next time I get the ball I'm going to stick it to him. You make those notes as a catcher.” [2]  [1] “Source: Joe Torre to call Brian Sabean,” ESPN.com News Services, June 3, 2011,  .  [2] R.B.

team sports house believes major league baseball should continue allow collisions
A clean hit will not heighten tensions between teams. Players recognize when a collision is “dirty” and when it is entirely within the rules and spirit of the game. After the Posey hit, a baseball columnist summed up “the consensus viewpoint” of baseball professionals and journalists: “It was a clean play.” [1]  In the 2011 playoffs, Texas Rangers Mike Napoli was barrelled over by Sean Rodriguez of the Los Angeles Angels. Napoli said afterward, “It was a fine, clean play. He was trying to score. I’m going to try to do the same thing if I’m trying to score and a guy is blocking the plate in that moment.” [2] As long as a player is not intending to hurt another and does not use unnecessary force, players on both teams are unlikely to hold grudges.  The threat of retaliation for “dirty” hits is actually a useful deterrent to gratuitous force. Players are much less likely to hurt each other if they know that there will be consequences for that behaviour.
