Why can't we tackle?

[SunsetBengal]

Too many attempts to land the "atomic shoulder". I see this in particular with Shawn Williams. Often he will be in position to make a tackle, but instead come flying in with his arms tucked, as if trying to make his shoulder a cannon ball. From what I have observed, it works less than half of the time. Someone needs to tell him to open his arms, and wrap them around the player. If an impressive hit is landed in the process, great. If not, at least you have doubled your chances of ending the play, at that spot.
