Walker certainly has the range to make shots from the arc. While she doesn't shoot a high percentage yet, she has good shooting form and will undoubtedly improve once she arrives in Storrs.
Agreed. Meg shoots roughly 85% at the FT line, which is a good indicator of her shooting ability. Her FG shooting is in the 40-45% range. Part of that is because she draws double and triple teams. At UConn, she will draw single coverage, learn which shots to take and which to pass up, and practice her shooting. She's the #1 recruit per most sources for a reason.
There have been "concerns" about Lexi's shooting as well. She's also only a little above 40%, but the situation is the same as with Meg. Lexi is not quite as long or quick as Meg, but she has nice form. She too will be a quality shooter at UConn.
Don't worry about Andi. She's been a shooter since at least 7th grade.
