Garlett was one of four experienced Blues - including Mitch Robinson, Brock McLean and Michael Jamison - recalled to face West Coast on Saturday afternoon at Etihad Stadium.
The small forward has played the past two games in the VFL and it was in the second half for the Northern Blues (against Footscray last week) that he exhibited the pressure required at senior level.
Garlett finished with two goals, 14 disposals and, more importantly, four tackles.
The 180cm forward - Carlton's leading goalkicker in 2013 - had little impact in the previous week's triumph over Frankston, although he gathered 13 touches with two tackles.
Wiley hoped Garlett had learned his value to the Blues and the need to play the team game during his spell in the VFL.
"Jeff is an important player for our side. He offers something different," Wiley said at Visy Park on Friday.
"And it was pleasing to see Jeff last week in the second half really get back to the form that he showed last year.
"He knows that he has to work hard, he's got a few tricks up his sleeve, but he's also got to come in and play what's expected of him from his other teammates and from the other coaches.
"Jeff's a very good defensive player, but he's also a very good offensive player. When he can get that right he becomes a very hard player to match up with."
OPPOSITION ANALYSIS: West Coast
Garlett and key forward Jarrad Waite paid the price for the Blues' poor start to the season and, in particular, Carlton's humiliating 81-point loss to Essendon in round three.
Waite performed strongly on his return in last Sunday's 28-point upset of the Western Bulldogs, booting three goals.
With Waite and Henderson (five goals) operating together in attack, the Blues had a potent forward set-up.
If Sam Rowe and Jamison can restrict the Eagles' tall timber - led by ex-Blue Josh Kennedy and Jack Darling - it will allow Waite and Henderson to play together up forward.
"Every game unfolds differently and West Coast are a completely different side, they've brought in three talls (Scott Lycett, Jeremy McGovern and Will Schofield)," Wiley said.
"But we believe that if we play the football that we've shown throughout the year, and particularly last week over four quarters, that if we can get the football into Henderson and Waite they're very dangerous, so we've also got to back ourselves.
"We were very pleased in a lot of aspects [of last week's game], but certainly we know that as each week progresses that we have to get better and there were probably some easy goals that the Western Bulldogs got.
"It's about continual improvement and we're certainly working towards that."
Wiley also denied there were any regrets about bringing Chris Judd back into the side last week.
BLUES MAKE FOUR CHANGES
Judd injured his hamstring just six minutes into his first game of 2014 and was one of three forced changes for the Blues this week along with Tom Bell (finger) and Ed Curnow (leg), while first-year player Patrick Cripps was omitted.
"No, no regrets at all," Wiley said.
"Chris is probably an unlucky player that it was in the mechanism of how he did his hamstring and that could have happened to anyone in the AFL.
"The good thing is that Chris is very positive, he's very professional and he'll be back sooner rather than later."
