I think Giardello would outbox Barkley like he did to Carter and take a UD

Agreed.

It would be the similar to Sumbu Kalambay where he outboxes the Blade to a decision win in 15 rounds which was the only time in his boxing career that Barkley lasted 15 rounds in one the last era of the 15 rounder.

If Kalambay outbox the Blade, then Giardello would do the same to the Blade as well by outboxing behind his jabs, movement and combinations to take a decision as well.
