Can you substitute やっぱり with さすが in 「疲れているが、やっぱり行くつもりだ」?


In such a sentence as 「疲れているが、 **やっぱり** 行くつもりだ」, can you substitute やはり with
さすが, with the meaning of "as one would expect", "also", "as I thought",
"still"? How would the meaning change in this sentence? I can't grasp the real
meaning of both adverbs in their daily usage.
