The visiting Indian team is without their star players Sachin Tendulkar, Virender Sehwag and Zaheer Khan. Instead, the team under Mahendra Singh Dhoni has the likes of Abhishek Nayar, S Badrinath and Murali Vijay in the ranks - players who are virtually unknown to the West Indies.
Dyson said the hosts would make a mistake if they take the Indian rookies lightly in the four-match ODI series starting at Sabina Park here on Friday.
"We don't know how they're going to perform and that's something we have to monitor as the series progresses," Dyson said.
Dyson arrived in Jamaica on Tuesday with six other West Indies players, including Trinidadian Darren Bravo, Dwayne's brother and the coach felt the youngster stood a good chance in the series.
"If you look at the possible side that could walk out on the field, we have an extra batsman, we have an all-rounder who is also a very good batsman, normal pace and reserved pace which is good and spinner. Hopefully, (Chris) Gayle will be providing back-up spin to him," he said.
