Terran are actually the slowest for getting a defensive unit out without compromising early game success.

Terran can be faster than Protoss, but unless it's reapers, those marines are gonna get zealot'ed up. If it is reapers, then the terran has likely given up early SCVs and will take time to recover, and if the reaper rush failed then they might be in trouble.

This is why Terran have the ability to wall off, or games against protoss and zerg would be over in the first 3 - 5 minutes every time.
