If you miss grabbing a Tryndamere that's about to last-hit your oom Cass, and you have the opportunity to grab them AWAY from them, you just killed someone because your whiffed your grab.
If you miss grabbing an ADC at low health for an easy kill for YOUR carry, it's a lost opportunity to be ahead of the enemy laners... which -could- prevent your adc from snowballing, which could hurt your team later on and even during laning phase.
If you miss grabbing someone before a team fight, you lose the opportunity of having an edge over the other team. If you grab a champion made to initiate who can do as such, then you royally **** your team over.
Blitzcrank is so incredibly high-risk compared to other champions that it's not even funny. He relies on the mistakes and unaware state of the enemy team. If they make little to no mistakes, you're going to have a tough time trying to overtake them.
