Ian Millward took heart from Castleford's doggedness despite their opening Super League defeat to favourites Warrington.
The Tigers were 28-0 behind with barely a quarter of the contest played, but a decent response had the home side sweating before they ran out 40-24 winners.
Millward said: "We were up against a really talented squad who are worthy favourites for Super League and for us it was really foreign territory, with eight new faces, and to see where our young kids were.
"It was tough early on as we had only two completed sets in the first 15 minutes, so had no ball.
"At half-time I was quite positive and in the second half our enthusiasm, toughness and desire was great, but on a couple of occasions our execution was just off when we looked a little bit rusty.
"I thought if we could have got one or two tries we could have made it a great last 10 minutes and really been pushing for the game. We blew a couple of chances but I'm really proud of the players."
Wolves boss Tony Smith said: "We were probably a little bit scrappy with the ball at times but I thought our defence was was pretty good for a fair amount of the game.
"But we did some really good stuff as well today and, with the amount of penalties in the match and the amount of ball turned over, you are going to concede a few points."
