Well, all of the choices were definitely pleasant surprises. No question.
I picked Barron and Tavon. Hell, I had pretty much given up on Tavon, so his performance really surprised me. Barron blew me away in terms of exceeding expectations. A backup hybrid player that performed at a Pro Bowl level? Wow!
Some others that were big and very pleasant surprises for me:
Case Keenum won 3 of 5 games.
Boras was 3-1 as interim OC under very difficult conditions.
McLeod made a believer out of me. I had underestimated him, big time.
Havenstein greatly exceeded my expectations.
Maybe not big, but still pleasant surprises were Longacre and Wichmann.
