Is this sufficient stats to justify Ramdin’s sacking?

Recently the West Indies Cricket Board (WICB) dropped experience wicket keeper batsman Denesh Ramdin from its squad to face India in the upcoming home series. Prior to his axing the 31 year old vented his anger on social media, seemingly because he thought his omission was not deserved. However, over the years he has done an excellent job behind the stumps for West Indies but has failed horribly in front of the stumps, with the bat.
Although he registered two half centuries in his most recent two Tests in Australia, the following details his performance in Test and First Class cricket to date.
Preceding those fifties during the tour to Australia, in 15 innings Ramdin failed miserably passing 30 just once while all of his other innings he contributed less than 30 to his team’s totals.

Selected to represent West Indies as a wicket keeper batsman, to date the Trinidadian has an ordinary return of 74 matches, 126 innings, 14 not outs 2898 runs at an average of 25.87, with just four centuries and 15 half centuries.
His ordinary return along with his form since 2014 may be the reason behind his sacking. Since the commencement of 2014, Ramdin has average 22.10 in 31 innings with a mere four half centuries. His returns are tenth on a list of 11 wicket keeper batsmen who have been involved in 12 or more innings.
Barbados wicket keeper batsman Shane Dowrich who averages 38.60 from 52 First Class games was named as Ramdin’s replacement for the upcoming series. In his first class career to date he has already scored three centuries with a top score of an unbeaten 131 to go with 14 half centuries. He is a rookie of two Test matches, both played against the Aussies during their tour of the Caribbean in 2015. He played as a batsman and made 70 in his debut match against a bowling line up comprising Mitchell Starc, Mitchell Johnson, Josh Hazlewood and Nathon Lyon.
Dowrich has scored 843 runs at an average of 49.58, with two hundreds and four fifties in 16 matches in the regional four-day tournament over the last two seasons. He averaged 51.25 from ten games in the 2014-15 season, and in 2015-16 he played six matches as wicketkeeper, at an average of 45.60. (In one match he didn’t keep wicket; his overall average for the season was 38.83).
Like Ramdin who is a product of the WICB Regional youth tournaments as a representative from the Trinidad team, the right handed batsman Dowrich was a regular member of the Barbados junior teams and went on to represent West Indies U-19 at the 2010 Youth World Cup in New Zealand. Since then he has shown potential in his batting ability, finishing sixth on the overall list with 229 runs at an average of 45.80.
Besides his attributes with the bat, Dowrich possesses the quality as a keeper and has been the most outstanding of the wicket keeper batsmen during regional tournaments for the past two years.
At present Ramdin is second to Jeffrey Dujon on the list for the most runs as a West Indies wicket keeper batsman. However, at 31 he has ample time to go back to the first class system to enhance his game and providing Dowrich is axed or injured make a stake to reclaim his spot in the team.
