      This deficiency is what accounts for boron being a strong Lewis acid, in that it can accept protons (H+ ions) in solution.

      This statement is incorrect. Lewis acids (like sp2-hybridized boron) are electron pair acceptors, not proton acceptors. Lewis bases are proton acceptors, and there are no lone pairs of electrons at the boron atom in typical compounds (BH3 or BH4- or derivatives).
