I'm like big, if he is better than Godbolt then take him for sure. I'd take another godbolt.
In any event, I am in agreement that we need another point guard, provided he has good ball handling skills. And I assume we offered Grooms because he has ball handling skills that Blair and Newell don't. Otherwise, I don't see the need for just another average juco guard. We could get by with Blair and newell. Now, if he has good D-1 handles, then he brings something to the table we don't have. At present, we don't have anyone on our team that can dribble. It is a little hard to play in the Big 12 with this deficiency, as we saw this year.
I also agree we need a good "big", but agree with this if he a good big. We actually have good post "numbers" on the team. Fitz, Neal, Osby, Thompson, CJ and Honore can all play in the post.
However, if we can't get another "good" big, with some real size, then I say our biggest need, outside of a point with handles, is a midsize wing with enough lateral quicks to properly defend the wing. We have pledger and Cam, but otherwise, we have to go small (newell) or big with less than necessary lateral quick to guard the wing on the perimeter (neal or osby). We had a h-ll of a time guarding the Olukemis, burks, hamiltons, etc this year. We were either too small or too slow. So, if Richardson has the lateral quicks to guard the wing sized perimeter players and is really 6'5 or taller, then I say we can use that. Arguably, Pledger isn't quick enough, I know some argue this fact. So, we only have either 1 or at most 2 that can properly defend man to man good size wings and I say we can use another one.
So, I don't know if we should sign Richardson ((haven't seen him) but if he fits the above profile, then I say sign him unless we can get a really tall and quality big that would play ahead of the several that we currently have.
