There are plenty of ifs everyone can come up with, if they had been playing anyone in the top 10 other than Chelsea and us they would have been absolutely mauled. They lost 4-1, goal difference means something.
You're assuming they would have definitely lost by fewer goals if they parked the bus. A two man deficit is a very big deal, no matter how you defend. The fact they kept the margin to a single goal until deep into injury time (and shut Chelsea out for 20 minutes after the second red card) really just proves their tactics weren't as terrible as you seem to think.
